Colloquy was originally commissioned in 1967 and was composed for soloist Sgt. Major David Maser and a symphonic band. It was  then performed in Carnegie Hall within the year, becoming a favorite of symphonic, jazz, and pop trombonists. The orchestra version was created in 1992 at the request of Ron Baron, principal trombonist of the Boston Symphony.

An emotionally connective piece of Americana, contemporary and romantic, influenced by the work of Aaron Copland and Leonard Bernstein, the work was conceived in one movement. However, this version includes a jazz-influenced solo that sounds almost improvised. Includes piano reduction for rehersal purposes.
