Adventurous clarinetist, composer and arranger dead at 86. His “50-year journey through jazz led him from writing the Woody Herman anthem “Four Brothers” through minimalist, drummerless trios to striking experimental orchestral works…

Among the half-dozen instruments he played, from bass flute to soprano saxophone, it was the clarinet that gave him a signature sound; it was a dark, velvety tone, centering in the lower register, pure but rarely forceful. But among the iconoclastic heroes of the late ’50s in jazz, he was a serene oddity, changing his ideas as fast as he could record them.” (New York Times)
