An American vocal group who recorded soul music for Stax Records in the late 1960s and early 1970s.

The group was formed in 1968 by Isaac Hayes and David Porter of Stax Records in Memphis, after one of the label's top acts, Sam & Dave, left Stax to join the Atlantic label. As leading songwriters and producers for the label, Hayes and Porter put together a vocal group with two male and two female singers, all of whom sang lead on some of the group's recordings. The original members were Norman West, John Colbert (aka J. Blackfoot), Anita Louis and Shelbra Bennett.
