Formed in Austin, Texas, in 1965, the 13th Floor Elevators were psychedelic pioneers, influencing the likes of the Grateful Dead and Janis Joplin, “led by outsider genius Roky Erickson, who combined offbeat spiritualism with crude R&B,” according to Allmusic. “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.” Erickson and his bandmates were known as vocal proponents of mind-expanding drugs, and when the frontman was arrested in Texas for the possession of just one joint, he pleaded insanity rather than go to jail for up to a decade. Erickson spent three-and-a-half years in a mental institution and was subjected to electroshock therapy and Thorazine treatments before being released in 1972. He eventually became a notable recluse along the lines of Syd Barrett, Brian Wilson, Daniel Johnston and Skip Spence. But Erickson (above, performing “Don’t Shake Me Lucifer” and “Two Headed Dog”) still occasionally found time to record and even tour. His most recent solo release, True Love Cast Out All Evil (stream it below), backed by Okkervil River, came out in 2010. “A tumultuous history hasn’t stopped the former 13th Floor Elevator from achieving greatness,” said NME. And Pitchfork added: “On this affecting and ultimately triumphant album, Erickson comes out on top.” His new tour launches today, and Erickson plays Rough Trade NYC on Tuesday and Wednesday. L.A. experimental rockers Death Valley Girls open both shows.
