Ray Anderson is an American jazz trombonist. Trained by the Chicago Symphony trombonists, he is regarded as someone who pushes the limits of the instrument, including performing on alto trombone and slide trumpet. He is a colleague of trombonist George E. Lewis. Anderson also plays sousaphone and sings. He was frequently chosen in DownBeat magazine's Critics Poll as best trombonist throughout the late 1980s and early 1990s.

George Gruntz was a Swiss jazz pianist, organist, harpsichordist, keyboardist, and composer known for the George Gruntz Concert Big Band and his work with Phil Woods, Rahsaan Roland Kirk, Don Cherry, Chet Baker, Art Farmer, Dexter Gordon, Johnny Griffin, and Mel Lewis.
