A composer and multi-instrumentalist who helped bridge jazz and classical music in postwar America, writing orchestral, chamber, and choral works threaded with jazz idioms while performing on piano, French horn, guitar, and pennywhistle. He was a fixture of the Beat-era arts scene in New York, collaborating with Jack Kerouac on some of the first jazz-poetry performances, and remained an active composer and performer for decades afterward.
