The legendary pioneer of the Chicago blues scene has just turned 79, but he is still one of the most exhilarating guitarists in the world, and still in powerful voice. Born in Louisiana, he moved north to be influenced by Howlin’ Wolf and Muddy Waters, and developed a passionate, driving guitar style that made him a hero for blues-rockers from Eric Clapton to Jimmy Page. It’s no surprise that the guests here include ZZ Top’s Billy Gibbons, who joins him on the stomping Wear You Out, and Van Morrison, who sings on the poignant Flesh & Bone, a tribute to the late BB King.
