ROBERT RANDOLPH & THE FAMILY BAND Perhaps it’s a vestige of his Pentecostal roots, but when Robert Randolph gets to rocking, it’s no surprise that audiences catch the spirit. The pedal-steel guitarist and his band put on a high-powered show that practically (and sometimes literally) demands you get off your tail and shake it. And who can resist, with funk grooves like “I Need More Love” and “Thrill of It” thumping along? Randolph was named by Rolling Stone as one of the “Top 100 Guitarists of All Time,” and during a hot performance he’s been known to kick over his chair and let the band go while he dances across the stage. The Family’s proclivity to jam is one of their hallmarks, and Friday’s show is name-your-own-price, so there’s no excuse for crying the paycheck blues. Get baptized in the funk; you won’t regret it. With T-Bird & the Breaks. Name your price. Sept. 28, 8 p.m. U.S. National Whitewater Center, 5000 Whitewater Center Pkwy. 704-391-3900. www.usnwc.org.
