Johnny Winter’s self-titled LP is one of a handful of albums released in the late ’60s that forged the alliance between blues and hard rock. In the process, the singer and guitarist displays boundless range: power-trio romps in East Texas swamp, acoustic moments haunted by Delta ghosts, and ballads crying with Memphis horns. Winter’s fretwork unifies all the wonderful variety. From beginning to end, but especially while slaying B.B. King’s “Be Careful With a Fool,” the imposing talent lets it rip with gale-force intensity.
