His blues: Morgan has cut three records. The first, 1994's Ridin' in Style showed a cocksure 23-year-old grappling with the snarling roadhouse rhythms of Jimmy Reed and Jimmie Vaughan; the second, '96's Louisiana Rain, widened Morgan's reach, burning through raw Stax-Volt soul, Chuck Berry, Robert Lockwood and Jimmie Rodgers, the fuel that ignited rock & roll in the first place. Small surprise, then, that Bo Ramsey produced Morgan's brand-new Lost Love and Highways (Hightone). Morgan's guitar work has become darker, denser, faster -- the opener, "Bullet from a Gun," sounds like a Billy Zoom-driven X reunion -- and his voice, all instinct and grime, has become a last-chance wail -- forget that he's all of 28 years old. Jon Penner and Chris Hunter, his rhythm section, not only rock, they move, heedless as a cyclone sweeping over a swamp. The faithful who wouldn't miss regular stopovers by Bugs Henderson, the Bel Airs and Duke Tumatoe shouldn't miss Morgan: This could turn out to be the most unexpectedly thrilling roots-rock show of the year.
