Rocco Scott LaFaro (April 3, 1936 – July 6, 1961) was an American jazz double bassist known for his work with the Bill Evans Trio.

Beginning in 1955, he was a member of the Buddy Morrow big band. He left that organization to work in Los Angeles. LaFaro spent most of his days practicing his instrument. He practiced with a clarinet book to improve his facility. Bassist Red Mitchell taught him how to pluck strings with both the index and middle fingers independently. For much of 1958 he was with Victor Feldman‘s band.

In 1959, after working with Chet Baker, Stan Kenton, Cal Tjader, and Benny Goodman, LaFaro returned to the east and joined Bill Evans, who had recently left the Miles Davis Sextet. With Evans and drummer Paul Motian he developed the counter-melodic style that would come to characterize his playing. Evans, LaFaro, and Motian were committed to the idea of three equal voices in the trio, working together for a singular musical idea often without the time stated.

By late 1960, LaFaro was in demand as a bassist. He replaced Charlie Haden as Ornette Coleman‘s bassist in January 1961. For a time, Haden and LaFaro shared an apartment. He also played in Stan Getz’s band between jobs with the Bill Evans trio. Around this time he received a greeting card from Miles Davis suggesting that Davis wanted to hire him.

In June 1961, the Bill Evans trio began two weeks of performances at the Village Vanguard in New York City. The trio attracted attention for its style. The last day was recorded for two albums, Sunday at the Village Vanguard and Waltz for Debby.
