A powerhouse soul belter and wailer, Mavis Staples doesn't have to play second fiddle to anyone, including Aretha Franklin, when it comes to pure, house-rocking, testifying authority. She's seldom gotten a complete album of quality material, but on this 1969 debut, she took half-baked material and made it memorable. "I Have Learned To Do Without You" wasn't a classic, but her vocal made it mighty close.
