King and Guy are among the stars who interpret Vaughan's own songbook in live performances backed by either his old band, Double Trouble, or the larger Tilt-a-Whirl Band. Bonnie Raitt, Eric Clapton, Robert Cray, Dr. John, and the late guitarslinger's big brother, Jimmie Vaughan (himself a major figure since his days with the Fabulous Thunderbirds) all pay gritty musical homage noteworthy for powerhouse guitar work. Whether clad in coveralls (Guy) or Armani (Clapton, of course), each reaches the same common ground in the soul-deep language of the blues; equally important, the choice of material points up Vaughan's sure sense of blues song form and a penchant for tough, frequently witty lyrics that fit snugly into blues traditions. The 80-minute concert also intersperses brief interviews with the principals, with the music building toward a satisfying climax in three high-octane jams featuring the headliners in lively exchanges. The DVD optimizes the full-frame visuals of the original videotaped special, and the 5.1 audio mix likewise fine-tunes the straightforward stereo mix with some added ambience. --Sam Sutherland
