William John Evans (1929–1980) of Plainfield, New Jersey began studying piano with his older brother Harry around age 5. … Bill moved to New York in 1955 where he studied composition and made connections on the music scene, the most significant of which came in 1958 when he was recruited by Miles Davis.
William John Evans was an American jazz pianist and composer who mostly played in trios. His use of impressionist harmony, inventive interpretation of traditional jazz repertoire, block chords, and trademark rhythmically independent, “singing” melodic lines continues to influence jazz pianists today.
