From his role in the Davis band, Chambers was the bassist in two rhythm sections. The first, with Red Garland on piano and Philly Joe Jones on drums, came to be known as "the rhythm section," that name featured on a celebrated album by saxophonist Art Pepper, "Art Pepper Meets the Rhythm Section". The second, with Wynton Kelly and Jimmy Cobb, made many sessions as a unit, recording albums with John Coltrane, Wes Montgomery, and by themselves under Kelly's name on albums such as "Kelly Blue".
