Rotary Connection was an American psychedelic soul band, formed in Chicago in 1966 and are best known as being the backing band for Muddy Waters on his psychedelic blues album Electric Mud. The highly experimental band was the idea of Marshall Chess, son of Chess Records founder Leonard Chess. Marshall was the director behind a start-up label, Cadet Concept Records, and wanted to focus on music outside of the blues and rock genres, which had made the Chess label popular. This led Marshall to turn his attention to the psychedelic movement. He recruited Charles Stepney, a vibraphonist and classically trained arranger as well as members of a little-known white rock band and a Chess receptionist named Minnie Riperton, who would later be successful in her own solo career. The band released their self-titled debut album in late 1967. It had various styles, borrowing heavily from pop, rock, and soul. The album also boasted an Eastern influence through its use of the sitar. The arrangements, brought to life by the Chicago Symphony Orchestra, imbued their albums with a certain dreamlike quality, emulated in I Am The Black Gold Of The Sun.
