Ramsey Lewis has long straddled the boundary between bop-oriented jazz and pop music. Most of his recordings (particularly by the mid-'60s) were very accessible and attracted a large non-jazz audience. In 1956, he formed a trio with bassist Eldee Young and drummer Red Holt. From the start (1958), their records for Argo/Cadet were popular, although in the early days, they had a strong jazz content. In 1958, Lewis also recorded with Max Roach and Lem Winchester. On the 1965 albums The In Crowd and Hang On, Ramsey made the pianist into a major attraction and from that point, on his records became much more predictable and pop-oriented. In 1966, his trio's personnel changed with bassist Cleveland Eaton and drummer Maurice White (later the founder of Earth, Wind & Fire) joining Lewis. In the 1970s, Lewis often played electric piano, although by later in the decade he was sticking to acoustic and hiring an additional keyboardist.
