About Us

At Buzz Music Group we have hand picked the best musicians around to take your wedding or event to the next level.

Our Musicians

A Music Agency You Can Trust

We believe that good live musicians elevate an event to a different level, creating memories you will cherish forever. At Buzz Music Group we love live music and we love weddings and events. So when Jonny and I both felt the need for a change in our career direction, combining our knowledge of music with another passion was a no brainer! From our lives as professional musicians we had the best in the field at our fingertips. We have a pool of wonderful musicians who we know to be trustworthy, reliable and simply the best players out there at the moment. They have played at many super high profile events as you will see from their profiles.

We don’t want hundreds of musicians on our books, only the best, and we believe in valuing them as the talented artists they are. We know you and your guests will love them!

We are making quite the Buzz! We love to hear great things back from out clients and the amazing experiences they have helped them have.

The music from the quartet was beautiful.

You are obviously all accomplished musicians and you did us proud. It was an absolute pleasure to meet you all.”

Bill Brown, Tatton Hall, Tatton Park

Their performance was excellent and they had everyone on the dancefloor from the start. The feedback that we received from our staff afterwards has been so positive! We wouldn’t hesitate to use USO again. Top class professionalism coupled with excellent musicality is what you get when you book USO.
