ZZ Top played their first official gig on the 10th of February 1970.
The band had formed in Texas by Billy Gibbons in late 1969 with drummer Frank Beard and bass player Dusty Hill making up the trio.
In '73 the band's third album Tres Hombres broke into the top 10 and the single La Grange became a minor hit.
In the 80's the band had their first top 10 hit with Legs and their eighth album Eliminator became their biggest seller.
Others 80's hits included Gimme All Your Lovin, Sharp Dressed Man, Sleeping Bag, Stages and Rough Boy.
In the 90's the band recorded a great cover of Viva Las Vegas.
In 2004 ZZ Top was inducted into the Rock n Roll Hall of Fame.
The band is still going after 50 years and last year played a run of shows in Las Vegas.
