Zoot Sims was an American jazz tenor saxophonist from Inglewood, California who began his professional career in the 1940s, performing with both big bands and small groups within the swing and cool jazz traditions. His playing blended swing phrasing and cool-jazz subtleties within the post-war tenor-saxophone tradition, and over a multi-decade career he moved between ensemble formats and studio recording, contributing to the mainstream evolution of American jazz.
