On One Kind Favor, King revisits the influential blues of his youth, but don't expect some acoustic front-porch Delta simulation. King, as always, transforms the music, employing his usual urban sophistication. At the same time, there's something special going on here. With producer T Bone Burnett building a bottom end that rumbles like a city bus, King pushes himself hard; no band of hard rockers out there can match the icon's jagged solo on T-Bone Walker's "I Get So Weary." Oh man, is it heavy.
