A young drummer by the name of Maurice White met trombonist and bassist Louis Satterfield while performing at Chicago's Chess Studios. At that time Satterfield was working at Chess as a musician, where he played on hit songs such as Fontella Bass's "Rescue Me." The duo later collaborated as part of a jazz group known as the Pharaohs. After leaving Chess to play in the Ramsey Lewis Trio, Maurice went on to start up a band known as Earth, Wind & Fire. He eventually expanded the band's sound to include a horn section called The Phenix Horns. Two of Satterfield's bandmates from the Pharaohs, saxophonist Don Myrick and trumpeter Rahmlee Michael Davis, joined the horn section, along with trumpeter Michael Harris.
