The ceaselessly innovative and searching composer and Butch Morris died yesterday in New York. He had been under treatment of cancer for several years. Morris was 65. He developed an approach to big band music that he called conduction. It made demands on musicians by insisting on intensive, intuitive listening, reaction and interaction. The effort involved adjustment to Morris’s highly personalized methods of conducting while simultaneously composing and arranging through a system of cues and hand motions.
