Sims, you see, is all showman. He'll bound from one end of the stage to another like a kid performing on air guitar in his bedroom: part clown, part star, a tour de force performance, all the while ripping off some of the tastiest licks since the Tootsie Pop. Employing the kind of irreverent sense of humor you'd expect from a band called the Gaza Strippers, their subjects have ranged from the virtues of masturbation ("Automat") and pimping ("Get 'em Down") to dieting ("Brainwasher"), murder ("Mommy Shot Daddy") and "auto" eroticism ("Throttle Bottom"). They're not above a cheeky cover either, such as their high-octane version of Love and Rockets' "Yin and Yang (The Flower Pot Man)." But in the end it always comes back to Sims' guitar pyrotechnics, which celebrate the big, silly attitude of '70s rock like AC/DC, delivered at a breakneck pace for the attention-addled TV generation. Think of it as high-concept junk food.
