Mavis Staples

As the voice of the legendary Staple Singers, soul belter Mavis Staples hardly qualifies as under-appreciated. But this Rock and Roll Hall of Famer and Lifetime Achievement Grammy-winner is in the midst of a glorious resurgence. 2007’s inspired We’ll Never Turn Back, focuses on gospel tunes she performed with the Staple Singers and the spiritually charged Stax/Volt anthems—”I’ll Take You There” and “Respect Yourself”—that put the family in the civil rights vanguard.
