Formed in Houston in 1970, this famed rock group now consists of three native Texans, Billy Gibbons and Frank Beard, both born in Houston, and Dusty Hill, a native of Dallas. Their Eliminator album had sold 10 million copies in the United States by 1996, and the group became one of the world’s most popular live attractions. In 1990 they appeared in the movie Back to the Future. Still going strong after 30 years, ZZ Top is among the nation’s most venerable yet popular old-fashioned rock groups.
