An all female American soul quartet, these ladies were some of the most prolific backing vocalists in 60's R&B, literally singing on dozens of hit records for other artists. Originally formed with Philly vocalists Dionne Warwick, Dee Dee Warwick and Doris Troy and Emily "Cissy" Houston. With burgeoning solo careers Dionne and Doris soon left, but Cissy found the group new voices including Sylvia Shemwell , Myrna Smith and Estelle Brown and they ended up on records by Wilson Pickett, Garnet Mimms, Aretha Franklin and others.
