The Charles Williams Quartet centers on the artistry of Charles Isaac Williams (C.I. Williams), a New York-based jazz alto saxophonist whose career spans influential sessions from the early 1970s through the late 1990s. Williams’ sound blends straight-ahead jazz with soul-jazz and funk-inflected textures, a synthesis that has drawn praise from critics and fellow musicians alike. While this page focuses on the quartet project and Williams’ broader contributions, it also highlights key recordings and collaborative milestones that shaped his distinctive voice in jazz.
