ZZ Top is an American rock band that formed in 1969 in Houston, Texas. The band comprises guitarist and lead vocalist Billy Gibbons , bassist and co-lead vocalist Dusty Hill, and drummer Frank Beard. One of the few major label recording groups to have held the same lineup for more than forty years, ZZ Top has been praised by critics and fellow musicians alike for their technical mastery. Of the group, music writer Cub Koda said "As genuine roots musicians, they have few peers; Gibbons is one of America's finest blues guitarists working in the arena rock idiom while Hill and Beard provide the ultimate rhythm section support."
