He started his musical career as a jazz musician and vibraphone player, and began work for Chess Records as a musician and arranger.[3] In 1966, Charles Stepney and Marshall Chess, son of Chess Records' co-founder Leonard Chess, established a new soul rock band called the Rotary Connection. Stepney was eventually appointed as the band's producer, to appear on Chess' subsidiary label Cadet Records. He went on to produce their 1967 self titled debut album and Aladdin, their 1968 follow up release.[2] As well as 1968's Peace and their 1969 album Songs. He also produced the group's 1970 album Dinner Music and 1971 LP Hey Love.[1] Paul Bowler of Record Collector proclaimed, "The six albums that Rotary Connection recorded under Stepney's guidance proved revolutionary; a glorious fusion of styles made essential by the simpatico nature of Stepney's lush string arrangements and [Minnie] Riperton's multi-octave, quasi-operatic vocals."[3]
Stepney went on to produce Rotary Connection lead singer Minnie Riperton's 1970 debut album Come to My Garden. In a November 1970 interview with Downbeat Magazine, Stepney exclaimed Minnie "has a soprano range of about four octaves, a whole lot of soul, she's good-looking and she's got the experience of Rotary behind her."[4]
The song "Spirit" was intended to uplift Stepney's spirit and to show all the gratitude that Earth, Wind & Fire had towards him. However, Stepney never got to hear the song. Maurice White spoke to Stepney on the morning of May 17, 1976, but later that day, Earth, Wind & Fire keyboardist Larry Dunn received a phone call, informing him that Stepney had died of a heart attack.[citation needed]
