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.
