What can you say about perennial rockers ZZ Top that hasn’t been said before? These guys have been together for almost fifty years and know how to bring a show to their fans. Heck, they could run through their set list in a deep REM sleep because they’ve done it so many times…all the way back to the Nixon years.

The trio brought their brand of Texas-fried Rock to Northfield’s Hard Rock Rocksino on Saturday night. The sold-out crowd was on their feet for the majority of the brisk 75-minute show. The short length didn’t seem to faze the crowd as the band played all their hits and even a cover of Hendrix’s “Foxy Lady.”

The night started with “Got Me Under Pressure” and continued with a few deeper cuts. Both “Foxy Lady” and “Gimme All Your Lovin'” shored up the middle of the show and then a litany of the band’s hits brought the show to a close.

“Cheap Sunglasses,” “Chartreuse,” “Sharp-Dressed Man,” and “Legs” were all offered prior to the first of two encores.

Frontman Billy Gibbons fresh off his first solo album, Perfectamundo, still has the vocal chops for a man pushing 70. His guitar playing is some of the finest in the business; he’s one of those axemen that doesn’t get the credit he deserves for his decidedly-original licks.

The band left the stage and returned for “La Grange” and “Tush” before exiting to a five-minute chorus of cheers. They returned and played Elvis’ “Jailhouse Rock,” before leaving the stage for the last time.

Working like a finely-tuned machine, Gibbons, Hill and drummer Frank Beard have stood the test of time; they’re one of a handful of outfits that have survived intact for such a long haul…most marriages don’t last as long as these three, and they’re showing no signs of slowing down.

ZZ Top is a band that, gulp, has legs.
