Four great blues harmonica players (James Cotton, Billy Branch, Charlie Musselwhite, and Sugar Ray Norcia) are featured in various combinations on this spirited disc, backed by a four-piece rhythm section (with guitarist Kid Bangham and pianist Anthony Geraci). Cotton and Norcia have solo pieces, seven numbers feature two harmonicas, and the lengthy low-down blues "Harp to Harp" has all four of the harmonica players taking turns soloing. Much of the material is jazz-oriented, including "The Hucklebuck," "TD's Boogie Woogie," and "Route 66," and the majority of the selections are instrumentals. Each of the harmonica players sounds inspired and the results are consistently exciting and swinging.
