Fashioned after Martha and the Vandellas and The Supremes (they were actually named after a 1970s Supremes album with just the 'e' changed to an 'i' in "energy"), the group was signed to Motown's Gordy subsidiary in 1977. They quickly found success with the R&B/pop hit, "You Can't Turn Me Off (In the Middle of Turning Me On)," which reached R&B #2 and U.S. #12.
The group would score a total of nine R&B hits before disbanding for solo careers in 1984.
