We will look out for you at Traders when we come back to your country again.
Thanks for everything,

Friends and Other Stuff (2015)
Hello Bob,
I wanted to reach out and see if you may be available to DJ the XXXXXXX middle school dance on Friday, December 11th. We had a DJ back out and I think we are coming to appreciate the level of service that you provided more. I apologize for not appreciating it in the past. I understand that this is a one off and we may not be able to get the same rate. However, I wanted to check with you before we reached out to anyone else. Please let me know if you are available. Thanks!




Pool Party (2005)
Bob Hartman of HardRock's DJ Service has been the sole DJ for Belair Bath and Tennis (BBT) in Bowie for 2 years. During the time he has provided his services for us, we have found his work to be both professional and courteous. Whether it be an adult function, children's party, or family event, Bob has always chosen quality music and provided great entertainment. He certainly lives up to his slogan: "We'll make it a blast!!!!" Bob consistently requests feedback and works with organizers to implement any and all suggestions. I would recommend the choice of HardRock's DJ Service for any function requiring a DJ. We, at BBT, hope to continue our working relationship with Bob Hartman for many years to come!

Car Show (2017)
We have attended the Indian Head Car Show each September for the last several years and that is how we first observed Bob Hartman as a DJ. While he had big shoes to fill as our favorite DJ, XXXXXXX XXXXXXX, had retired! So, of the number of DJ’s that were met at different shows, Bob Hartman stood out as someone we would like to contact and discuss his future as a DJ for our show. 

This is a testimonial to Bob Hartman of HardRock’s DJ Service after he DJ’d our 7th Annual Baden Volunteer Fire & EMS Department's Car, Rat Rod, Truck & Bike Show "Under The Lights" on June 9, 2017:

Mr. Hartman, Bob, fulfilled all the characteristics that were desired and expected of an outstanding DJ! His voice is and was clear and distinct as he spoke using his up-to-date sound system. He continually followed the program throughout the evening as requested by naming the numerous sponsors that supported this Fire & EMS Department’s show as a fundraiser.  

Bob took the time when necessary to interrupt the music to announce the door prize ticket winners and direct them to our registration tent as well as when he saw additional children on the show grounds, he took the initiative to direct them to the registration tent to pick up their ‘Kids Choice’ card and their ‘Kid’s Judge’s" badge. He made everyone important at our event!

As Bob was contracted to do this Fire & EMS show, he asked the preference of music that should be played during the event and 50’s as well as old County Music was chosen. He did not hesitate with those choices and his selections were perfect as the background for those 161 show cars and additional bikes that cruised in as they glimmered later in the evening ‘under the lights’ waiting for the judges’ decisions!

Car Show (2012)
I just wanted to thank HardRock's DJ Service for your great support at our 2012 car show, it was great working with you.  Your selection of Oldies Rock/Contemporary Christian Rock was a perfect fit for our event.  Your professionalism and strong desire to meet your customer's needs was evident and welcomed.  On behalf of Indian Head Baptist Church and the Town of Indian Head, thank you.

Car Show (2011)
 Archbishop Neale School hosted its 1st Annual Car Show on Saturday, October 8th, 2011. After a rescheduled rain date, the weather cooperated producing a gorgeous day! All who came thoroughly enjoyed themselves, including the kids. Father Kosty of St. Catherine's Parish blessed all of the cars in the show. Trophies were awarded to top 20 cars as voted on by all participants. Each of the vehicles was unique and in impeccable condition. One Car was awarded the Archbishop Neale School Best of Show Award. A special "THANK YOU" goes to all of the volunteers, HardRocks DJ Service, and all of the sponsors who made the day a success. We look forward to next year's car show, scheduled for May 19, 2012.
Bob Hartman of HardRocks DJ Service and his associate did a wonderful job. I would recommend the choice of HardRocks DJ Service for any function requiring a DJ. We here at Archbishop Neale School, Development Office hope to continue our working relationship with Bob and his associate for many years to come.

Hi Bob,
     I just wanted to thank you for making our event a success. I really appreciate the discount you extended for your services but more importantly your professionalism. Being a non-profit organization and entertaining our wounded Troops from Walter Reed is always a special day and you helped make it complete.
     One day away from the hospital for these soldiers is like one day of sunshine. I look forward to hiring you next year for our Fundraiser Event and Car Show / Barbeque.

            We would like to thank you again for entertaining at our recent charity event. A good time was had by all! You played a great mix of tunes, enjoyed by all the different age groups represented. The kids especially enjoyed the fun activities, and we also thank your wife for getting things going! If we plan another event, you will be the first person we call! Thanks again!


Theme Party (2014)
Dear Bob,

So sorry it has taken a bit of time to get this letter out but since our party I have been nothing but busy!
How do you thank someone who is the prime reason our community dock party was such a success! People are still talking about it!
When you are creating a themed party, in an outdoor open area for a giant group of people, it is not an easy task. You, Bob, were so refreshing to work with. You listened, understood what we needed, very clear on what your needs were and you became the Star of our party!
So many people came up to me to let me know how great the party was. My 2 favorite comments were, "Best Party Ever", and "We were dancing all night!".
Thanks so much for being the best DJ, dressing the part, and the CD's.
So sorry you had to use your headlights to breakdown your equipment. Next year I am planing to have the party first weekend in June, stays light longer! Let you know the theme next year.

Girls Dance Party (2013)
    Bob,Wow!!!! I have had 2 incredible dance parties this past year.  The first was on Saturday May 4th, what a blast... we had so much fun!!!!  Everyone loved it.  When I first mentioned I wanted to have one I had some people look at me funny.  Well they just have no clue.  It was fantastic!!!  The weather was perfect and the music put us in the mood for dancing the night away.  I won't elaborate on the the window dancing and no one has video to prove it!!!!
My 2nd party was on Friday Oct. 18th needless to say I was concerned about the weather....  All dancing is outside on deck.  That nights forecast was the same as May 4th!  The stars aligned, there was a lunar eclipse, a science teacher and the partying started.  Bob and I didn't think we could top my last party, but it happened!!!!  More window dancing and fireball!!!!     
I recommend Bob services and will hire him again.  I also recommend a Girls Dance Party... It is a blast and you will have so much fun. One girl suggested our husbands come next time???NO, are you kidding me?????  I have these because my husband is out of town!!!  It's a GIRLS DANCE PARTY!!! Thanks Bob.

Wedding (2004)
On May 1, 2004, my first (of three) daughters, was married. After many months and hoping that everything would be perfect, there was one thing I never doubted. I was completely confident that our DJ, Bob Hartman was ready for the task.
Rachel's wedding had a Celtic theme with a bagpiper at the church. We wanted to continue this atmosphere at the reception, during the meal. After an enthusiastic introduction of the wedding party, Bob kept our mood with the wonderful Celtic music he chose. Our guests loved it! After dinner he went right into the bride and groom's special choices for dancing.
Now, you may think this is what any DJ would do... what he's getting paid to for. But Bob is more than a DJ, he's a planner too. He has a schedule and he keeps to it while everyone has a good time, especially the bride's mother. There are no dull moments when guests are wondering what's going on. I received many, many compliments on Bob's talent at keeping the party going. Bob is professional, charming and so easy to work with in those hectic weeks before the big day. Bob Hartman of HardRock's DJ Service is sure to make any event special.

Wedding (2005)
Hi Bob!
Can't thank you enough for the super job you did at Shannon's wedding. Everyone seemed to be having a "blast"! You gave the kids what they asked for and made the evening go smoothly for all. I'm so glad you and Rose could be there for the festivities and your expertise and enthusiasm was contagious.

Thanks again!

Wedding (2008)
Hi Bob and Rose --
Thanks so much for making are special day great!! I think everyone young and old thoroughly enjoyed themselves. You guys are super and I would definitely recommend you to anyone.

Thanks again!!

Mr. Hartman (HardRock's DJ Service),
We would like to extend our sincere gratitude to you and your wife for all the hard work you put in to making our wedding reception such a success. You kept everyone on the dance floor and I'm certain that every person who was in attendance had a wonderful time. We truly appreciate the way you informed us of the upcoming special "moments" but gave us the freedom to alter that slightly throughout the evening. We have received many compliments, both from friends and family, on how smoothly the evening went and that is definitely a tribute to your work. Thanks so much!

Dear Bob & Rose,
I never doubted that you would do a great job at our wedding! Not only were you extremely easy to work with, but very well organized and thorough. Rose was wonderful as well, with all the extra help she provided as well as just making sure everything ran smoothly. You guys make a great team. I have had a lot of compliments about you and have nothing but wonderful things to say myself. You guys were truly awesome and kept the reception going all night long. I can't tell you enough how thankful I am that we found you to DJ our wedding. Oh and not to forget you did a beautiful job at the ceremony as well ;)

Thank you again,
Christina & Jim Petite

Thank you so much for the excellent service that you and Rose provided to Andy and me at our wedding. Everyone had a blast. I will recommend you to anyone in search of a great DJ!!! Thank you again.

Wedding (2006)
Our daughter Rachel was married on a beautiful Saturday in August 2006. We were thrilled to have our terrific friend Bob Hartman as our DJ and his wonderful wife Rose as the “un-official” wedding coordinator. We only wish Bob and Rose had been at the wedding ceremony to coordinate it as well as they did the reception.
Bob is truly a professional. He met with us six months before the wedding to discuss the reception. Because he has been a DJ at so many weddings he was able to take us through a typical reception. He was able to point out the pitfalls and mistakes that can be made. He helped us pick the music that would span the generation gaps without alienating anyone. He was very diplomatic and was able to get my daughter and I to agree about the kind of music to be played. Unlike others involved with the wedding Bob kept in touch with us during the many months of planning. He called both my daughter and I to reassure us.
When the big day finally happened Bob and Rose were there for us. From the time our guests arrived at the reception until the wedding party got there, Bob kept the guests entertained. He kept the music moving. From the time we walked in until the reception was over Bob was in control. Rose was our unofficial wedding coordinator. She lined up the large wedding party according to the long list of names Bob was to announce. She prompted me before all of the important reception milestones occurred, and she did everything with a smile. Bob was also good enough to play sentimental favorites that had our friends and family dancing. He played a wide variety of music that pleased everyone and had the three year olds to the Grandmothers dancing. We couldn’t have asked for more. Hardrock's DJ Service was the best, put simply Bob made our reception a Total Blast!

Wedding (2007)
We want to thank you for providing DJ Services for our wedding reception, Monday, December 31, 2007. The music you provided was just what we requested, a mixture of Classic Rock and Oldies, mixed with songs familiar with the younger group in attendance. Your choices of music seemed to get all ages on the floor from grandparents to grandchildren. The music volume was perfect, providing good background music allowing our guests to freely visit with each other, yet inviting, for those who wanted to dance. Also, we appreciate your willingness to take requests from those in attendance. All this was provided with less than three weeks notice. Thanks for helping create a comfortable relaxing atmosphere on our special day which everyone truly enjoyed.

Thank you very much for helping to make our wedding reception wonderful. Everyone had a great time and the music was awesome! We'll gladly recommend you to friends and family!

Dear Bob and Rose,
We wanted to thank you for doing such a great job for our wedding, on October 11, 2008. The music you played was great and accommodated everyoneʼs taste. You were able to play all of the requests and actually got everyone on the dance floor (which is a challenge with our families). Everyone had a great time. We will definitely recommend you to all of our friends.

Thanks again,
Christa & Dave

Wedding (2009)
Dear Bob,
Thank you so much for the awesome job that you did at our wedding. You seemed to have something for everyone and really kept a great tempo for the evening. It was a great feeling seeing all of our guests engaged, and on the dance floor. Everyone had a wonderful time! I'd also like to thank you for your professionalism throughout the entire process. Everything from your initial meeting with us, to the last dance was a real treat. Thanks again and we will definitely recommend you to our friends and family.

I can not thank you enough for being the DJ at our wedding. You kept the party going, played great music, and got everyone dancing. Everyone at our wedding said you were "Wonderful!" and we will recommend you to everyone we know! Thank you again for making our special day a little more special!

James and Rachel Malone

Wedding (2010)
Thank you again for being the DJ at our wedding! We were impressed at how organized and thorough the entire process was. You and Rose were easy to work with. You had ideas that we had not thought of to add that special touch. We are thankful for these memories of our families and friends coming together at one time dancing and having a spectacular time. We also want to thank Rose for sticking it out in the heat at the wedding ceremony! We will definitely recommend you to others.

Wedding (2010)
Dear Bob,
       Sam and I wanted to thank you and your wife, Rose, for helping to make our wedding day so special.  You couldn’t have made the process easier for us, especially since we were doing the planning from the other side of the country!  From our initial planning meeting, to our follow-up e-mails and telephone calls, you were always thorough, helpful in your recommendations and professional.   We wanted our wedding to feel personal and intimate, and to find vendors that we felt comfortable with and enjoyed working with, and we certainly felt that way with you and Rose from our very first meeting!  On the day of our wedding, we really appreciated the way Rose gently guided us through the reception, letting us know as each key moment was coming up.  It made the entire evening feel effortless and really allowed us to enjoy ourselves and spend time with our guests.  We received many compliments from our guests about the great music selection you played during the cocktail hour and dinner, and we know they had a good time dancing after dinner!!  Our wedding day was truly the happiest day of our life, and we cannot thank you enough for being a part of it.

Melissa and Sam Liggett

Wedding (2012)
Dear Bob and Rose,
We cannot thank you enough for the wonderful job you did last night at our daughters wedding.  Not only was the selection of music you played perfect, but so many of our guest remarked that they had never enjoyed a DJ and the music as much as they did last night. Our guests were able to enjoy dinner time conversation while appropriate music played and then later, when the dancing began, there was music for all tastes and ages. 
         Your service is top notch and both of you were a pleasure to work with.  We recommend you highly.

I just wanted to take a moment to thank you and your team at Hardrock's DJ Services for providing the entertainment at my wedding on November 17, 2012. My husband and I were so happy with all that you did to entertain our family and friends and ensure that the event ran smoothly. I had so many compliments that night....just thought you should know that we really appreciated all that you did. Dave and I are thrilled to find out that you will also be the entertainment at our fire station during our 2013 Installation of new officers! We can't wait to see you again ;)

John and I would like to thank you so much for DJ'ing our wedding! You, Rose and your assistant were so professional and fun! We really appreciated you letting us know exactly when the next dance or event was going to happen. And the glow sticks you gave the kids was so sweet! It was such a nice touch. Thank you again for being part of our perfect day. 

With Love,
Ashley and John

Wedding (2014)

Hardrock DJ’s owner, Bob, was so easy to work with, even from afar as we planned our wedding from the other side of the country. He was always professional, and courteous of our time in every conversation, making sure we were getting exactly what we wanted. Once the wedding day rolled around, everything was ready to go before guests arrived, and the music kept everyone on the dance floor all night! Our guests commented on how much fun they had and what a great musical selection there was – thank you so much for helping make the night so memorable!

Wedding (2014)

We had an amazing experience with HardRock’s DJ Service. Bob Hartman was great to work with! With all the craziness a wedding can bring, Bob helped to calm my husband and I’s nerves. Bob is very organized. He not only provided us with fantastic music but also a great timeline for reception. I had no worries the day of my wedding! That is a big deal for a bride to say! Bob was very easy to get a hold of when we had any questions or comments to share. Bob checked in with us several times before the wedding to make sure the timeline for the day was perfect- and it was! He and his helper kept the reception moving and everyone had a great time! I wish we could do it all again! My husband and I highly recommend HardRock’s DJ Service!

Wedding (2014)

We just got married this Sept. 2014 and we are so glad we got to work with HardRock’s DJ! Bob was very professional throughout the whole process, from the first conversation to the clean up after the wedding. We met with Bob a few times before the wedding to go over song choices, he was much more prepared than we were! Bob was able to help us find the perfect song for every moment of the wedding! When the big day finally came around, it felt as though we didn’t have to lift a finger! It was such a relief to know Bob had everything under control and there was nothing I needed to worry about! People were dancing and singing along all night! We couldn’t have choose a better DJ!!

Thanks again HardRock’s DJ!

Wedding (2015)

Hi Bob,
Dave and I would like to thank you for the fantastic job you did at our wedding. Your music selections for our party were great and everyone loved the fact that you didn't have the music playing too loudly. I want to also compliment your assistant. Very professional given his young age. You will definitely be our choice for a DJ for any future
events we have.

Carol and Dave Wilson 

Wedding (2015)

Our wedding was scheduled for March 2015 at Chesapeake Beach Resort & Spa and we needed a local awesome DJ for our reception. Bob, (DJ HardRock) came recommended by a close college friend. From the first meeting we had months before the wedding, Bob came off as personable and very organized. It was apparent from the beginning that he had years of experience of weddings under his belt and he had timeline down to a science. He also reminded us that this was our wedding and he let us be creative and offered suggestions when we needed help. Sure enough, the day ran seamlessly as he and his staff worked with the venue behind the scenes and kept us on track. Our guests loved the music choices and talked about it for months after the wedding reception.

Good Afternoon Bob,
Todd and I both wanted to thank you so much for your excellent DJ services at Stephanie and Josh's wedding. We couldn't have been any more pleased, and we received numerous compliment from the guests.

Thank you again,


Wedding (2018)    

Hi Bob,
Thank you so much for doing such a great job at our wedding last month. Our guests had such a great time, and we heard several specific compliments about the music. Thank you also to you and John Paul for keeping us on track and being our emcee for the evening. Everything was perfect, and we had a great time too. We will certainly recommend you to anyone looking for a DJ in the future.
Thanks again,

Post Wedding Celebration (2015)

In September 2015 I hired Bob Hartman as our DJ for a post wedding celebration. He turned our party into an "event!"' Bob made it a point to check in with me several times to make sure my needs were being met. Our guests also enjoyed how easy he was to work with. Bob answered every request. If you are thinking about hiring a DJ for your event, I highly recommend Bob Hartman. I also thought his prices were extremely reasonable.

Hi Mr. Hartman,
Just wanted to drop you a quick note and tell you how "very pleased" we were with the DJ Services that you provided at our 50th Anniversary on February 2, 2019.  With over 200 people in attendance, we have only had excellent responses from our guests about your choice of music throughout the entire evening.  I hope you enjoyed our family and friends as much as they enjoyed you and your young assistant; Sorry, should remember his name but I don't.  He as well was very cordial and responsive to our requests.  

Must warn you, when we plan another get together or two, you will be our first choice for the music.  

Thanks again and hope to see you soon!!

Hi Bob --
Just wanted to send you and HardRock's DJ Service a quick note of thanks for a wonderful party to celebrate our 50th Wedding Anniversary.  Everyone told me they enjoyed the party and the dancing to "our songs" from many years ago.  It was a pleasure working with you to plan this special event (you could not have been any more accommodating) and I definitely will refer your services to my friends.

Thanks again --

50th Wedding Anniversary (2005)
Dear Bob,
      Thanks for a fantastic evening of music, fun & dancing. Your hard work in researching old music from the 50's paid off. Everyone had a wonderful time...old, middle aged and even the very young. You did a great job, including all and keeping the party hopping! Our parents are still talking about the great time they had at their 50th. We'll plan something for their 60th, after we rest a little. Mom's feet need a rest, she danced every dance I do believe. I can't end without thanking your wife for coming and keeping everyone in the know of today's dances, please thank her for us. Thanks again for a wonderful event, all thanks to a great DJ the heart of the party! Thanks for helping to make two special people in our lives very happy.

DJ Bob,
We just wanted to take a moment to thank you for the wonderful job you did playing at our parents 50th Anniversary party at the Crofton Country Club. I knew I was in good hands from the beginning. It is very apparent that you take your work seriously, and strive to provide the very best service to your clients. Many of our guests commented on how good the music and the flow of it was. If we ever have another celebration we will certainly be calling you.

Thanks Again,

Dear Mr. Hartman,
I want to personally thank you for the job you did at my parent’s 50th wedding anniversary party. Everyone had a great time and loved the music. Your selection of music appealed to all in attendance from age 2 to 82!!! You kept the party going smoothly even when we threw you a few unexpected curves.
All in all, it was a pleasure to work with you and I would not hesitate to recommend you to anyone who is looking for a DJ.

Thank you,

          My wife and I were so very pleased with your DJ service at our 50th Wedding Anniversary Party.  Your song selection had the variety that perfectly fit the wide range of ages in attendance.  In addition, you very appropriately judged the mood at all times and made choices of what to play at the exact right time to maximize the fun.  Everyone, toddlers to seniors, were up and dancing for the entire evening.  All of our guests had a wonderful time.  Even the venue wait staff commented about the fun level.  The event was even more successful than we had hoped for.

16th Birthday Party (2004)
Just wanted to thank you for helping to make the 16th Birthday Party we had for our daughter and her friend such a great success! As you know, I was slightly apprehensive about the music you might play. But alas, you were correct in assuring me that you would play music appropriate for a sixteen-year-old audience. The party was a tremendous success (despite the weather!) - you were able to accommodate all the teen's requests - even for "Swing Dance" music!

Thanks again - and please feel free to contact me should you need a reference.

Sweet 16 Birthday Party (2006)
I just wanted to thank you for making Casey's Sweet 16 party such a success. Although there were alot of teenagers there, it didn't seem like it because all of them were on the dance floor! The lights, fog and music made it seem as if they were in a dance club -- right in our own backyard. The pictures turned out great too! All of the kids had such a good time ~~ which is exactly what we wanted. Thank you for being so easy to work with, for all of your suggestions and advice, and for the great music! We'll definately be seeing you soon!

Dear Bob,
Thanks for DJ'ing at Alexa's 16th birthday party at our home. You were very easy to work with and talk to and you did a super job the night of the party. All of the teens had a really good time and probably could have danced for another two hours! Thanks also for playing my song! I highly recommend your services to anyone who is having an event where the music is an important factor. We hope to see you for our next party (in a few years!).

Dear Bob,

Please forgive me for taking so long to send this. Thank you so much for being DJ at my daughter’s Sweet Sixteen. Everyone had so much fun! It was a small gathering and the kids could have had a not so fun time, but it was great! All of the kids told us that it was great and they loved the music. My husband and I appreciated that you played some music for my husband and I and our friends. We even got to waltz and it was really neat watching our daughter teach her friends how to waltz! You were prompt and organized and made the breakdown of the party so much easier. I will remember your website and recommend you to others!

Thank you so much for helping us make Ashley and Joel's 18th Birthday a success! It has been such a pleasure getting to know you and your DJ business over the past 6 years. You have always been such a reliable, professional business with just the right amount of personal touch! We appreciate that you took the time to make sure the music would make the 18 year olds happy while keeping the content appropriate. We look forward to seeing you again. Ashley's graduation and Dillon's 18th birthday are just around the corner.

Again, thanks so much for everything!

Birthday / Halloween Party (2005)
Bob Hartman was recommended to me through St. John Vianney Church in Prince Frederick, Maryland. I was considering hiring a DJ for my daughter's Birthday Party which had a Halloween theme. I was looking for a DJ to play popular music without explicit lyrics. Bob fit the bill!

My children attend a local parochial school and are not afforded the opportunity to attend school dances. They love music and were thrilled to have the opportunity to have a DJ at the party. They had a wonderful time and enjoyed the music tremendously. They danced and participated in the games that Bob organized and especially enjoyed the prizes he provided. Parents at the party also took part in dancing and watched on as their children had a wonderful time.

I can't say enough about Mr. Hartman....he worked well with me and understood my concern regarding lyrics. He kept everyone happy with the music selections he provided. I would use him again in a minute and hope to do so soon. The kids are already asking me when I'm hosting the next party! Thanks for a job well done!

Cookout for Family and Friends (2013)
Mike and I can't thank you and Rose enough for the wonderful time everyone had at our cookout this past Saturday. We have had many cookouts at our home over the past 34 years we've been married. This one was truly the best. The interaction you and your wife have with the guests is unique. We continue to get comments from those that attended about how much they enjoyed the music and the service you provided. You and Rose are the best. We're looking forward to using your services for many years to come. I'm already getting emails from those that attended that they would like to come with us to Trader's to see you again soon.

House Party (2006)
Dear Bob,
I want to thank you for the great DJ'ing job you did at our house party. It certainly rocked our block! The invitees couldn't stop talking about it for months afterwards and they want to know when our next party is. I think you were a large part of the reason it was such a success.
You were the perfect DJ and you played just the right (and appropriate) music for our kids and the adults too. Thanks for all you do and I can’t wait till the next party.

50th Birthday Party (2004)
I hired HardRock's DJ Service for my wife's 50th birthday party. Upon doing the invitations I found out that there were other birthdays and wedding anniversaries all around the same time. So I called the party summer fun. I must admit that Bob Hartman did a fantastic job. There were over seventy people there at the party and I heard nothing but great praises for an excellent job by HardRock's DJ Service. The music selection was great. The contests and special additions that Bob did were an unexpected add-on and a pleasure. A good time was had by all. I would definitely re-hire and highly recommend HardRock's DJ Service for any occasion.

50th Birthday Party (2008)
Mr. Hartman,
Thank for your awesome ” DJing” at my husband’s surprise 50th birthday party. You played the perfect combination of zydeco, 70’s, 80’s and a few modern cool songs (Thanks Mrs. Hartman!)
As many of us know, music brings us back to certain times that have etched memories on our hearts forever, and your choice of songs certainly brought us back to the years we treasured and laughed at. Many of my guests commented on just how great the music was and it definitely put everyone in the mood to party. Who can’t resist a little Foreigner to get you going??? Nothing better than a good cigar, a great hand of cards, dear friends, a “ beverage of your choice” and some rockin’ music!!! It all adds up to one incredible party. Thank you for making this milestone a memorable one! We will definitely call you when I turn 50! YIKES!!

50th Birthday Party (2010)
Hi Bob,
        Thank you for rocking Joyce’s (Big 50) surprise birthday party.   Most DJ’s blare the music at the crowd, I really appreciated how you spread the speakers around the room so people wanted to dance but could also carry on conversations.  You had everyone from 4-80 years old on the dance floor having a great time. 
        I remember all the teen club dances you did for Saint Pius X.  I will never forget the night when my son’s basketball team had just come from winning the championship.  You called all the boys up on the stage and played “We are the Champions” as all the girls cheered.   Those boys thought they were studs.  You made a lasting memory for all those boys.
        You have a great intuitiveness to understand and give the customer what they need.   That’s why you’re the BEST.

Thank You,

50th Birthday Party (2012)
Hi Bob,

What a great time everyone had at my husband's 50th Birthday Bash! I love that you played anything and everything that our guests wanted to hear. I think we wore a hole in the dance floor! Thank you for working out a deal with us to play an extra 2 hours as well. I loved that our friends didn't want to leave. This all means that the party was a success.

Thanks again for making Mike's birthday a HOOT!

60th Birthday Party (2014) 

 Bob and his team were a delight to work with! I planned a surprise 60th birthday party and didn’t want to have to manage every detail, like the entire music list. Bob got some back ground information, showed up on time and gave us fabulous and professional service. The music was great and he was flexible with the schedule of activities. Everyone had a great time and I would recommend him highly to anyone looking for a reasonable DJ. His attention to detail was only superseded by his friendly and collaborative attitude. He made the party an easy success!

Thanks Again,

70th Birthday Party (2010)
Hi Bob,
We can't thank you enough for all that you did to make my mother-in-laws 70th surprise party such a blast!
          The music was perfect and everyone had a great time dancing and singing. It meant a lot to Diana and her sisters when you played their special songs. The evening made such great memories and we are so glad that we had a fabulous DJ to help make it all happen. (The children loved having you there too!) We will always remember Hardrocks DJ service when anyone has a special event.

Thanks a million,

80th Birthday Party (2004)
Mr. Hartman,
Thank you so much for the wonderful job! I think everyone had a good time. I know my mom did! In fact, my aunt emailed this morning and said she had a great time! I had a good DJ who played a variety of music. She was glad she could enjoy dancing since she doesn't get to do that often. Thank you again. I'll call you again when I need a DJ.


103rd Birthday Party (2015)

So sorry Bob that it has taken me so long to send this to you.

Your participation as D.J. for my Fathers 103rd Birthday was spectacular. You provided more than I could have hoped for. I can't tell you all of the positive feedback I have received from all of my guests.

I will definitely be using you again.

It was obvious that you were one of the crowd. You more than met any expectations I had. You were so willing to accommodate any requests or needs that we had. Give me a couple weeks and I will be sending you a little extra since you did such a wonderful job. I will also be sending the picture link in case you want to use some of you that the photographer captured.

Thanks Again and looking to work with you again.

College Graduation Party (2017) 
What a wonderful night we had this past Saturday thanks to your DJ services. You played great music all night long that had everyone up and dancing!

You understood that we had quite a mix of people invited and really played a great variety of music.
Thanks for playing all of Meghan's favorites as well as a few of her mother's;)
We had such a great night and you were a big part of it.
I didn't expect all the glow necklaces, bracelets and the rings for the kids, what a generous bonus!

We will be sure to call you for any future events, hopefully soon!
With a grateful happy heart,

Hi Bob,
         Thanks for making my daughters college graduation party more fun than any of us imagined.  Everyone ages 21 to 60+ had a blast and most of the credit goes to you.  We can't thank you enough for making the memories even more special.  When we need a dj again there is no doubt that we will call you.

Class Reunion (2006)
Dear Bob,
Please accept my sincere apology for the delay in writing to you. With everyone’s busy, hectic summer schedule, our DuVal High School Reunion Committee members finally found a date to get together.
It is not hard to believe that everything said was extremely positive. Some of the comments were: “It was great that the DJ actually played songs that we requested”, “The DJ was involved, but not obtrusive”, “He was extremely efficient”. One of our committee members stated that “Having you as the DJ worked out great. It was the one thing of the evening that we did not need to worry about”. I, myself personally, appreciated the fact that you were so willing to help us out when ever asked and especially with our “Senior Moment Trivia Questions and Answer Game”. Everyone seemed to have a great time trying to remember things of the past and being rewarded with a gift too. Thank you for completely handling that for us. We really appreciate you working with us whenever asked.
Thanks Bob for all your help in contributing to the success of our DuVal 30th Class Reunion. It was a pleasure working with you, and we will certainly keep you in mind for any upcoming events.


School Dance (2005)
Dear Bob,
I wanted to write this letter in reference to the services your company, HardRock’s DJ Service, has provided for us over the last 3 years. I want to begin with thanking you for providing such excellent, reliable, fun and flexible services. Scheduling dances and other events for young people (6th – 12th grade) can be challenging given today’s culture and music.
You seem to have a special gift and talent for selecting music that is appropriate for our Catholic Christian environment, YET appealing for all the young people who attend. Your creative style of lighting and special effects makes it fun and exciting for the youth. As a matter of fact, our dances have consistently been well attended not only by the youth of our parish but from the surrounding parishes as well. Since our young people have requested having dances more often, these dances have become a monthly event here at our parish. Our young people look forward to the dances you DJ. Your great service, reasonable costs, and flexible scheduling make it virtually a hassle free event to coordinate and plan. I look forward to continuing our great working relationship.

School Dance (2003)
Bob Hartman of HardRock's DJ Services performed at my son's school dance. His rapport with the students and knowing their music preferences was so helpful. He kept the kids interested, involved, and happy. This was my first time organizing a dance, and I could not have done it without Bob. You will not find a more professional DJ, or businessman. I will definitely hire HardRock's DJ Services again. His main concern was that the kids had a good time. Parents, staff, and chaperones did, too! I would recommend the services of HardRock's DJ Service. He is adaptable to all ages and occasions. He is a likeable personality and that is immediately evident.

Hi Bob,
I am writing to thank you for your outstanding efforts at our 8th grade dance this year. Your selection of music was right on and got everyone on the dance floor. Students raved about your work in school over the next few days and asked that we get you back for our picnic. We invited you back and we were not disappointed! I appreciate the efforts you made to arrange a visit beforehand to survey the site and talk with me about my expectations for the evening. You did everything you said you would to make our event a successful one and our students and staff really benefited from your organization and commitment. Thank you!

Church Picnic (2005)
The performance of Bob Hartman of HardRock's DJ Service during our recent church picnic was absolutely tremendous! Bob's attention to detail, his flexibility, and his keen sense of the "crowd atmosphere" all contribute to his ability to ensure a great time. This is the first time that we've had a DJ at our annual picnic. From now on, it will be mandatory! Bob was able to flawlessly provide a mix of music that appealed to a wide range of people, and I received many comments regarding his selection. Bob's sense of what will "go over" well with what I'm sure was a difficult audience is a testimony to his professionalism and his craft. We will definitely ask him back time and time again.

New Years Eve Gala (2013)
I had to take a moment to send a big "THANK YOU!" to you for a great New Year's Eve Gala at St. Joseph's Church in Pomfret, MD.  The evening began with beautiful and quiet music, just like we requested, so people could talk, mingle and eat.  The dancing began and the floor was packed.  The variety of music was wonderful.  The best compliment I can give is that people are asking about next year, and if there is a next we know who our DJ will be.  I would highly recommend you and hope to see you next year.  Give my best to your lovely wife, Rose.  Have a blessed 2013.

Dear Bob,
Thank you so much for making our daughter's First Communion celebration an absolute success!! Since this was the second time we've used your DJ services, I knew it would be good. But, in fact, you exceeded our expectations! Always professional and pleasant and so engaging! And the music selection was phenomenal!! Our guests ranged from the ages of 7 to about 70 and you pleased them all, with everything from the current top hits to popular line dances and even to reggae. Thanks to you, everyone had a BLAST! Thank you once again and I'm looking forward to our next "event" together.

Club/Bar (2006)

DJ HardRock Bob is a fantastic compliment to our lounge. He offers a wide range of music to please the crowd at the club. He plays rock, rap, progressive, top 40, dance, oldies, classic rock, and the list goes on! He somehow manages to keep the people dancing. He has a very crowd-interactive program. The customers love his trivia questions.
Most importantly, Bob is dependable. He is always professional and is a pleasure to deal with on a regular basis. I’m always extremely busy and just knowing he’s there is a relief because he takes care of everything!
Crooked I Sports Bar & Grill in Chesapeake Beach, Maryland strongly recommends HardRock Bob for any occasion! We’re sure he can handle any venue that comes his way!

Company Holiday Party (2019)

Good Morning Bob, 

I just want to thank you for helping to make our holiday celebration a success.  It’s not always easy to please a crowd with a demographic as diverse as our group of 130 Nurses, but you pulled it off.  There was something for everyone and we all had a great time.  You were easy to work with and very accommodating to our needs.  I hope to have an opportunity to work with you in the future for other events we may have. Thanks again Bob.


Company Holiday Party (2007)

Thanks Bob, for another wonderful Christmas Party !! I continue to receive comments from attendees that they had a great time - enjoyed the music - that you played exactly what they like. I know its hard to please everyone - but your variety of music did just that for our annual dance. Please contact me when you start your schedule for the next holidays.

Thanks !

Company Party / Awards Ceremony (2009)
March 2009
Dear Bob,
Thank you for helping make the GST Annual Gala a wonderful event. I really appreciate your willingness to work with me as the demands of this Latin theme party evolved. You arrived early and had all of your equipment in place well before the guests arrived. When the “live” entertainment was late for the evening, without being asked you played Latin music until he arrived and set up his equipment. You worked closely with us to have suitable music for the special dance recital. After the awards portion of our evening was over it was your turn. As requested you played a wide variety of music. You played Latino music, to the Grateful Dead, onto Country then Jazz, then Glenn Miller and the president of GST’s favorite Phantom of the Opera. The music you choose had quite a few of us up and dancing. I received a several compliments from my co-workers. Some of the things they said were:
• Ramon said, “I liked the music. I can dance to anything. I dance better to that music.”
• Karin said, “The music was good. It looked like everyone was dancing.”
• Larry said, ”He played a lot of different music for different people.”
• Jan said, ”I liked the DJ. I think he did a good job.”
• Linda said, “I always like his DJ-ing services. Bob and Rose do a wonderful job. Bob is always very professional.”
• Amy said, ”I liked the music. He was playing a lot of the music I requested.”
• Mark said, “I was just waiting for the dance music to start. When I heard Glenn Miller start I knew I had to dance.”
I appreciate working with a true professional. You were able to segue from the Latin themed evening complete with a dance demonstration to a regular let loose have a good time party. I think more people stayed longer for this party than ever before. Thank you again for making it a really enjoyable evening.
