His double music life: “As William O. Smith, he pioneered unorthodox techniques for his instrument and developed ways to notate them for other players. Composers like Luigi Nono, Pauline Oliveros and Gunther Schuller fashioned works that took advantage of Mr. Smith’s uncommon virtuosity. His own compositions were performed and recorded by eminent artists like Mr. Schuller, André Previn and Marni Nixon. As Bill Smith, he enjoyed a lively career as a jazz clarinetist. He was admired for his bright tone and buoyant swing, most visibly in bands led by [Dave] Brubeck.” – The New York Times
