If The 13th Floor Elevators didn't invent the psychedelic sound, they were certainly among it's earliest explorers with the original release of this album in the August of 1966. Clever use of instruments and sound effects, along with the ponderous lyrical explorations of an acid trip, The 13th Floor Elevators expanded minds and the music industry. This twin LP reissue features the remastered original album in mono sound. It also features the stereo version, with the songs arranged in the order the band originally wanted fans to listen to them. Each album is made of 180-gram vinyl. They come in a handsome replica gatefold album cover.
