Philadelphians Leonard Davis, Joe Harris, Chuck Whittington, and Jimmy Williams were Double Exposure, one of the more prominent groups on the mighty disco label Salsoul. The quartet was one of the most soul-steeped on the roster. This had more than a little to do with their background as a soul group called United Image, which got together in 1966 and recorded a single for Stax in the early '70s ("African Bump" b/w "Hit Man"); and, being from Philadelphia, the group couldn't help but soak up the sounds laid out by the likes of Harold Melvin & the Blue Notes, the Stylistics, the Spinners, and the Intruders. Despite the thick soul leanings of Double Exposure's sound, they failed to light up the U.S. charts. However, they did fare much better in clubs and enjoyed more success in England.
