William John Evans (August 16, 1929 – September 15, 1980) 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.

Born in Plainfield, New Jersey, in 1929, he was classically trained at Southeastern Louisiana University and the Mannes School of Music, in New York City, where he majored in composition and received the Artist Diploma. In 1955, he moved to New York City, where he worked with bandleader and theorist George Russell. In 1958, Evans joined Miles Davis‘s sextet, which in 1959, then immersed in modal jazz, recorded Kind of Blue, the best-selling jazz album of all time. During that time, Evans was also playing with Chet Baker for the album Chet.

In late 1959, Evans left the Miles Davis band and began his career as a leader, with bassist Scott LaFaro and drummer Paul Motian, a group now regarded as a seminal modern jazz trio. In 1961, ten days after finishing an engagement at the New York Village Vanguard jazz club, LaFaro died in a car accident. After months of seclusion, Evans reemerged with a new trio, featuring bassist Chuck Israels.

In 1963, Evans recorded Conversations with Myself, a solo album using the unconventional technique of overdubbing himself. In 1966, he met bassist Eddie Gómez, with whom he worked for 11 years.

Many of Evans’s compositions, such as “Waltz for Debby“, have become standards, played and recorded by many artists. Evans received 31 Grammynominations and seven awards, and was inducted into the Down Beat Jazz Hall of Fame. Evans grew up in North Plainfield, New Jersey, the son of Harry and Mary Evans (née Soroka). His father was of Welsh descent and ran a golf course; his mother was of Carpatho-Rusyn ancestry and descended from a family of coal miners. The marriage was stormy because of the father’s heavy drinking, gambling, and abuse. Bill had a brother, Harry (Harold), two years his senior, to whom he was very close. On September 15, 1980, Evans, who had been in bed for several days with stomach pains at his home in Fort Lee, was accompanied by Joe LaBarbera and Verchomin to the Mount Sinai Hospital in New York City, where he died that afternoon. The cause of death was a combination of peptic ulcer, cirrhosis, bronchial pneumonia, and untreated hepatitis.^[10] Evans’s friend Gene Lees described Evans’s struggle with drugs as “the longest suicide in history.
