Welcome to Trilogy Band!

We are very honored when you take the time to consider the “Trilogy” band for your entertainment needs. Since 1974, we have provided the greater bi-state area with the best in live music at affordable rates.

We take pride in having the top musicians, vocalists, stage appearance, audio and lighting equipment, and energy off the stage which has maintained our standard of excellence and a reputation for quality that we have earned performing in excess of 4000 engagements in the last 46 years. Our work ethic on every engagement is second to none when it comes to going that little extra to make your engagement or party a success which is evident in the many testimonials you will find in our website.

50 Years of Excellence

Experience really matters in the entertainment business along with trust and honesty in your product/presentation. “Trilogy” does not use pre-recorded tracks of instruments or vocals; all songs are performed live by the band. “Trilogy” does not substitute musicians; the band you hire will be the band you get at your event.

“Trilogy” does not gouge its clients and add on any hidden costs to your event such as sound and lighting engineers and added labor costs to set up our equipment. We have the highest quality equipment in sound reinforcement and LED lighting and we know how to run our equipment to make it “concert perfect” and still be able to have conversations.

In 50 years in the entertainment business, we have never received one complaint or refunded a client over a performance that was not up to par. That is an amazing fact and quite an accomplishment that few bands can claim or for that matter many Fortune Five Hundred companies can claim. We have a perfect record with the Better Business Bureau and for your information carry liability insurance.

Our Brand Has Grown Over the Last 50 Years

Bill thank you for being a part of Bridgeton's Fourth of July Celebration! Trilogy did a fine job and we at the city were pleased that you could be part of our festivities. Bridgeton prides itself on having a family friendly event and this year's lived up to the billing.

Mayor Terry Briggsfrom the City of Bridgeton, Missouri

You and the rest of the Trilogy band were fantastic last weekend. Everyone had a blast, such that friends have expressed how much they'd like to have the wedding weekend on repeat. For me the bride, it was important to have good music and a full dance floor at my wedding as well as being a fun party: thank you for making that happen! And, thank you for being willing to stay the extra half hour to keep the party going and learning our special songs. In short, Brad and I could not be happier.

Lindsay and Johnregarding their wedding reception at the Worlds Fair Pavillion on September 6. 2015

Trilogy Band made our wedding reception a hit - people continue to compliment us on our choice of bands. They get the party started and played great songs from all different decades - including current. They even learned a song that wasn't on their song list…they did a great job. From the first meeting, Bill made us feel comfortable by being professional, yet flexible, and the whole band was so nice to work with. I would definitely recommend Trilogy Band!

What a great group!! Our guests were complimenting the band to us all evening! From the introduction of the wedding party, to the last song of the night, these guys entertained us and gave us the music we wanted! Thanks to Trilogy for a beautiful job! We will recommend Trilogy to any one who wants first class and professionalism!

Lindsay and Corey Cathcart

Trilogy did an amazing job. The professionalism of the band and quality of sound was terrific. Our guests danced on the first song, and didn't quit until the last. I highly recommend them.

We used Trilogy Band for our daughter's wedding! They are fabulous and will not disappoint you! They play the music you want to hear and the dance floor is always full! Bill MC's the reception and is so efficient and organized! The band members and singer are so talented and professional! Our son, who plays the guitar, also joined the band for a few songs! We also had 2 band members during the cocktail hour play a keyboard and sax for background music, excellent! Thanks Bill and band members!

We used Trilogy for our wedding reception music and cocktail hour music. Musically they were phenomenal and the interplay of fabulous vocals coupled with really well balanced and professional instrumentals made for an amazing sound. They were very professional and they were very easy to work with. Many of the guests complimented us on the band… Bill and his team made the process seamless and really made the reception a blast. Thank you Trilogy for a beautiful evening and we highly recommend them!

Bill, "amazing, great, awesome!" Jenny and I heard these words and many other compliments from our wedding guests about your band all night long. You guys were perfect and made for a truly memorable evening, and how about that Horah for 20 minutes.... incredible! Beyond the night thanks for meeting with us and for learning all of the songs we requested. We will promote Trilogy to everyone! Thanks!

Bill, wanted to thank you guys for the AMAZING job on Saturday night! You guys stole the show,everyone could not stop talking about how great the band was on Sunday when we all got together. Thanks for being so flexible with us and for adapting so quickly to things. We can't wait to come and see you guys play a show! Thanks!

Katie and Matt Navoon their wedding reception on 10/10/2014 at the Piper Palm House.

Trilogy did a fabulous job playing at our wedding reception on June 30, 2012! From the day we signed the contract to the end of the event, Bill Grosch and his band were incredibly easy to work with. They are all very talented musicians and kept the party rocking all night. Their rates are an incredible bang for the buck. They know a large variety of music, but will even learn a special request before the event if they don't know a song that you'd like to have played. My only regret is that I was too busy visiting with our guests and didn't get to dance enough! I highly recommend this band!

From Wedding Wire.com

Bill, Trilogy orchestrated the most amazing wedding and reception our guests have ever experienced! The personalized touches, unique to your band, were enjoyed by all. You were fun to dance to with an upbeat rhythm. You maintained the perfect volume where guests could easily socialize while many danced. You added entertainment and humor throughout the evening and kept the flow from each event seamless. Everyone was impressed with your array of talented singers and musicians. Thank you for an amazing evening!

How We Treat You

“Trilogy” really gets what the client wants in their event and we are able to really connect with our clients. Our level of communication with the client prior to the event is second to none and we encourage face to face meetings at the location of the client’s choice.

We arrive for the event at least 2 hours before the start time and the fact that we have been in the business so long gives us the advantage of knowing all the venues, wedding planners, photographers, video folks, country club managers, hotel banquet managers, florists, to coordinate all their efforts and pull off a great party.

It is amazing, when we run into couples that we played their wedding reception 35 years ago and they still rave about the job we did for them. What is even more amazing is that our leader Bill Grosch can probably remember their reception and their first dance song!

Our Mission

Although there has been a great deal of change in the entertainment business in the last forty two years with the challenges of disc jockeys, track bands, and so many bogus band awards to confuse the client, our emphasis has always been to treat the clients with honesty, respect, and class. We have been able to do this while still keeping our cost very competitive.

Our band was formed with the mission statement “to provide the best live musical entertainment at fair and reasonable prices while creating an atmosphere of enjoyment for the clients as well as the musicians.” We are proud to say we continue to strive for this goal and have shared in many great memories within the “Trilogy family”

Thank you,

The “Trilogy band members”
