When ZZ Top came out of Houston in the early ‘70s, they played a fuzzy mix of blues and boogie rock that totally suited their appearance and background. With slight variations over the years, that’s pretty much what they’ve stuck with for the past four decades. After a somewhat stumbling start, the trio (Billy Gibbons, Dusty Hill and Frank Beard) locked into 1973’s ‘Tres Hombres’ with a crowded-barroom intensity that shot them straight into the Top 10. Ten years later, they slapped a bunch of synth-driven pop rhythms on top of their beer-soaked rock ‘n’ roll and scored the biggest album of their career, ‘Eliminator,’ which yielded radio classics like ‘Gimme All Your Lovin’ and ‘Sharp Dressed Man’ and made them instant MTV stars. Since then, ZZ Top have released a steady stream of records and have regularly hit the road for their still-entertaining stage show.
