The Moving Sidewalks was a 60's psychedelicblues-rock band, most notable for giving future ZZ Top guitarist Billy Gibbons his start in the music business. The group members were Billy Gibbons (guitar), Don Summers (bass), Dan Mitchell (drums), and Tom Moore (keyboards). Gibbons founded the Texas psychedelic group in the mid-1960's and quickly drew a large following, especially in the Houston "Teen Scene". They recorded several singles and one full-length album, Flash. Their single "99th Floor" was a hit and topped the charts at #1 in Houston for six weeks.
