(1999); "A Festival Journey," (1992) and "Ring Shout Concerto," (1974) for percussion, written for Max Roach and premiered by Max Roach and symphony orchestra; and "Concerto for Piano" (Jazz Trio) and symphony orchestra (1983) written for Billy Taylor and performed with the Springfield Symphony Orchestra.
