Palmer, a former rock musician and Memphis Blues Festival cofounder best known for his bylines in The New York Times and Rolling Stone, had already chronicled the saga of Southern blues in his seminal book that provides the film's title. He's an astute guide, and Mugge underlines this role by pairing him with British rocker Dave Stewart (Eurythmics), whose avid interest in the music makes him an effective foil.

The film's real triumph, however, rests in the team's success in capturing modern day blues survivors and inheritors playing in the bars, juke joints, and barns of delta country. Palmer, who had returned several years earlier to the delta to capture these artists for his scrappy Fat Possum label, introduces us to the now-amplified but still elemental blues of R.L. Burnside, the late Junior Kimbrough, Jessie Mae Hemphill, Roosevelt "Booba" Barnes, and other keepers of the faith. Mugge, whose profiles of Al Green, Sonny Rollins, and other musicians probed their cultural and artistic contexts with intelligence and sensitivity, captures both the music and the milieu in crisp color footage. Deep Blues thus triumphs as a testament to the blues' deep roots and an unintentional eulogy for Palmer, who would pass away in the mid-'90s just as the gut-bucket music of Burnside and Kimbrough served notice that the blues were alive and kicking. --Sam Sutherland
