ZZ Top

The Texas-based blues rock outfit ZZ Top rose to prominence in the early 1970s with its dirty brand of southern rock and wailing guitar solos. After releasing its 1971 debut album, fittingly titled ZZ Top's First Album, the band established its raw, earthy sound and attitude with fuzzy guitars and rollicking rhythms. Each of the band's subsequent releases throughout the decade earned critical acclaim and a fair amount of radio play, proving that the three-piece band's Texas drawls and dirty jokes resonated with fans outside of the Lone Star State. ZZ Top continues to release its bluesy southern rock music and remains one of the most easily identifiable acts around with two of its three members sporting bushy, chest-length beards.
