ZZ Top formed after the demise of Moving Sidewalks, Gibbons' previous band. Within a year, they signed with London Records and released "ZZ Top's First Album" (1971). Subsequent releases, such as their first top-ten album "Tres Hombres" (1973) and the singles "La Grange" and "Tush", gained extensive radio airplay. By the mid-1970s, they had become renowned in North America for their live act, highlighted by their performances during the Worldwide Texas Tour from 1976 to 1977, which was a critical and commercial success.
