Based in Houston, the Moving Sidewalks were a '60s psychedelic garage quartet. The group famously featured singer-guitarist Billy Gibbons and drummer Dan Mitchell prior to their forming ZZ Top. Inspired musically and conceptually by Roky Erickson and the 13th Floor Elevators, the band's sole full-length album Flash was released in 1969. This reissue includes the non-LP bonus single "99th Floor."This is a new, unopened CD in its original packaging.
