Guitarist Robben Ford has led parallel careers. There's the virtuosic white blues musician who jammed with Jimmy Witherspoon as a teenager, and there's the superclean session player and fusion-jazz cat of L.A. Express and Yellowjackets fame. These roles merge on "Supernatural", produced by Susan Rogers (known for production work with Prince and Barenaked Ladies). Unfortunately, what comes out is a mediocre blue-eyed soul singer who has neither the voice nor the songs to match his guitar chops. Many of the tracks settle into listless studio funk grooves substituting polish for passion. Only when Ford reaches back to the blues for Paul Butterfield's "Lovin' Cup" does he crack a sweat. By that time, it's too late.
