The 13th Floor Elevators were one of the pioneering bands of psychedelic music; many have cited them as the first true psychedelic rock band, and if they weren't, they certainly predated most of the San Francisco bands that gave the sound a global audience. The Elevators played a bracing fusion of garage rock and genre-defying musical exploration powered by Roky Erickson's feral vocals and rhythm guitar, Stacy Sutherland's concise but agile lead guitar work, and Tommy Hall's amplified jug playing, the latter of which gave them a sound unlike any other in rock.
