Taj Mahal has always been a more inclusive, eclectic musician than even some admirers understand; his work was never simply or totally blues, even though that strain was at the center and seldom far from anything he performed either. That's the case with this newest collection, a 12-song set that includes splendid covers of Muddy Waters and Howlin' Wolf tunes, but also equally respectful, striking renditions of soul standards such as "Mockingbird," with special guest Etta James, and "That's How Strong My Love Is." There are also strong Mahal originals like "Blues Ain't Nothin'" and "Strut," with Mahal singing and playing in his wry, delicate, yet forceful way.
