The daughter of Texas bluesman Johnny Copeland hit the Cotton Club stage in Harlem when she was 8, and this sultry blues singer never looked back. Her strong, soaring vocals recall the power of Etta James, with a bawdy, raucous edge that blends R&B, gospel and blues. She's never been much of writer, relying on longtime producer/ mentor John Hahn for her best tunes. After four albums of generally fierce, chest-puffing blues, she toned down the intensity on her last disc, 2009's groovy Never Going Back, leaning on a star cast including John Medeski, Chris Wood, Marc Ribot and members of Col. Bruce Hampton's band. —Chris Parker
