Roots of Bill Evans

Oliver Edward Nelson was an American jazz saxophonist, clarinetist, arranger, composer, and bandleader. His 1961 Impulse! album The Blues and the Abstract Truth (1961) is regarded as one of the most significant recordings of its era. The centerpiece of the album is the definitive version of Nelson's composition, "Stolen Moments". Other important recordings from the 1960s are the albums More Blues and the Abstract Truth (1964) and Sound Pieces (1966), both also on Impulse!.

John Alfred Mandel was an American composer, multi-instrumentalist, and arranger of popular songs, film music and jazz. The musicians he worked with include Count Basie, Frank Sinatra, Peggy Lee, Anita O'Day, Barbra Streisand, Tony Bennett, Diane Schuur and Shirley Horn. He won five Grammy Awards, from 17 total nominations; his first nomination was for his debut film score for the multi-nominated 1958 film I Want to Live!. In 2011, he was named a Jazz Master by the National Endowment for the Arts.

Rocco Scott LaFaro was an American jazz double bassist known for his work with the Bill Evans Trio. LaFaro broke new ground on the instrument, developing a countermelodic style of accompaniment rather than playing traditional walking basslines, as well as virtuosity that was practically unmatched by any of his contemporaries. Despite his short career and death at the age of 25, he remains one of the most influential jazz bassists, and was ranked number 16 on Bass Player magazine's top 100 bass players of all time.
