Bluesman Elmore James was inspired by the local performances of Robert Johnson to take up the guitar. It was, in fact, a number by Johnson ("Dust My Broom") that became James’ signature song and laid the foundation for his recording career. First cut by James in August 1951, “Dust My Broom” contains the strongest example of his stylistic signature: a swooping, full-octave opening figure on slide guitar. His influence went beyond that one riff, however, as he’s been virtually credited with inventing blues rock by virtue of energizing primal riffs with a raw, driving intensity.
