ZZ Top (pronounced "zee zee top") is an American rock band from Houston, Texas, formed in 1969. The group consists of founder Billy Gibbons (guitar, lead vocals), Dusty Hill (bass, vocals) and Frank Beard (drums, percussion). Initially rooted in blues, ZZ Top's style has evolved throughout their career, with a signature sound based on Gibbons' blues guitar style and Hill and Beard's rhythm section. Their lyrics, often embellished with sexual innuendo, focus on their Texas roots and humor. Popular for their live performances, the group has staged several elaborate tours.

ZZ Top formed after the demise of Gibbons' previous band, Moving Sidewalks. 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 made them national stars and was a critical and commercial success...
