Back in the Ak — it feels good,” said ZZ Top singer-guitarist Billy Gibbons at the start of a sold-out show the band played earlier this year at the Akron Civic Theatre. “We’ve been coming around here for four decades — same three guys, same three chords,” he told the audience. Though Gibbons and bassist Dusty Hill now have a bit more gray in their beards, over the course of four decades, the self-described “little ol’ band from Texas” has remained a constant in the ever-shifting rock universe. Their new album, La Futura, represents a bit of a departure as producer Rick Rubin got the guys to play with a bit of a mean streak. Jamming with the Black Keys prior to cutting the record might have had something to do with the more contemporary sound. "We dig 'em lots," Gibbons says when asked about the Keys. "We thought the trio were the minimalist end of the spectrum yet they got us slimmed with just two. Black Keys do their thing as we do ours — we're kindred spirits so there's a mutual admiration among us for sure." The band's set list for tonight's show will be a mix of old and new tunes. And you can bet your beard that all them will rock hard.
