There’s no greater disservice a music critic can do to Jukebox the Ghost than compare the trio to Ben Folds Five. Considering that both bands center around a singing keyboardist, though, it’s understandable. What sets Jukebox the Ghost apart is Ben Thornewill’s dynamic and uninhibited vocals, paired with a relentless whimsy and optimism in his lyrics—an attitude that’s far from the anger and melancholy that colors Folds’ output. Of course, the trio is comprised of recent graduates of GWU who haven’t had enough time to truly experience the exquisite agony dished out by employers, estranged spouses, or student-loan officers yet. Given the fact that the members have so far managed to bypass the cubicle farms and make the band something of a full-time effort, their charming Peter Pan sensibility looks like a wise strategy. JUKEBOX THE GHOST PERFORMS WITH THESE UNITED STATES AT 7:15 P.M. AT FORT RENO PARK, 3950 CHESAPEAKE ST. NW. FREE. (202) 355-6356.
