Oliver Edward Nelson (June 4, 1932 – October 28, 1975) was an American jazz saxophonist, clarinetist, arranger, composer, and bandleader.
He is perhaps best remembered for his groundbreaking 1961 Impulse! album The Blues and the Abstract Truth, widely regarded as one of the most significant American jazz recordings of the modern jazz era. The album features the definitive version of the jazz standard "Stolen Moments". Other important recordings from the early 1960s are More Blues and the Abstract Truth and Sound Pieces, both also on Impulse!.
