13th Floor Elevators, the seminal psychedelic band helmed by Roky Erickson, are set to reunite at the Levitation festival in Austin, Texas, which takes place May 8-10. It's the first time the surviving original members—Erickson, Tommy Hall, John Ike Walton, and Ronnie Leatherman—will have performed together since 1967. "Special guests" are promised for their set.

"When we were going on we weren’t very appreciated, but now the young people dig us," Hall told the Austin Chronicle. "With the younger generations’ knowledge and their use of weed for good purposes, they understand the information. Once we have these ideas, it should change us physically."

13th Floor Elevators will close the festival on May 10. As previously reported, Tame Impala, Spiritualized, the Flaming Lips, Mac DeMarco, the Jesus and Mary Chain, Primal Scream, DIIV, Lighting Bolt, Metz, HEALTH, Thee Oh Sees, and many more are also set to perform.
