Though T-Bone Walker's '40s recordings are his most well-known, he was a force to reckon with in his later years too. One listen to his almost feral take on 1962's "I Wanna See My Baby" or his 1970 live team-up with teen phenom Shuggie Otis for a blistering guitar duel on "Mistreatin' Blues" makes it clear that his gift was the lifelong kind.
