For a nice break in your listening routine, try some jazz from Rich Matteson:
Easy Street
Life's a Take (Digital Only) - Rich Matteson & Red Mitchell
Pardon Our Dust, We're Making Changes - Rich Matteson Sextet
He plays in a manner totally different from traditional euphonium style. Rich was instructor of jazz at North Texas and a founder of the Matteson-Phillips TubaJazz group. He's very innovative and plays jazz in a style I like very much. I also learned from him how to build high range. Great player!
