Riding the waves of an evolving Feminist movement and the sexual revolution, the “girl groups” of the 1960s gave way to a more progressive look and sound for female singers in the 70s. Groups like Labelle, The Pointer Sisters, First Choice, and Sister Sledge took R&B, jazz, soul and even country music to a new level. Music journalist and essayist Christian John Wikane interviewed four women who helped power these groups to the pinnacle of the 1970s popular music scene: Rochelle Fleming, Nona Hendryx, Ruth Pointer, and Kathy Sledge.
