ZZ 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.
