William John Evans, known as Bill Evans ( August 16, 1929 – September 15, 1980), was an American jazz pianist and composer

Evans worked in a trio setting. He is widely considered to be one of the greatest jazz pianists of all time, and is considered by some to have been the most influential post-World War II jazz pianist. Evans's use of impressionist harmony, inventive interpretation of traditional jazz repertoire, block chords, and trademark rhythmically independent, "singing" melodic lines continue to influence jazz pianists today. Unlike many other jazz musicians of his time, Evans never embraced new movements like jazz fusion or free jazz. Born in Plainfield, New Jersey, Evans was classically trained, and studied at Southeastern Louisiana University. In 1955, he moved to New York, where he worked with bandleader and theorist George Russell. In 1958, Evans joined Miles Davis's sextet, where he was to have a profound influence. In 1959, the band, then immersed in modal jazz, recorded Kind of Blue, the best-selling jazz album of all time. In late 1959, Evans left the Miles Davis band and began his career as a leader with Scott LaFaro and Paul Motian, a group now regarded as a seminal modern jazz trio. In 1961, ten days after recording the highly acclaimed Sunday at the Village Vanguard and Waltz for Debby, LaFaro died in a car accident. After months of seclusion, Evans re-emerged with a new trio, featuring bassist Chuck Israels.
