Sat. April 5

 It can look like a rugby scrum up there on stage when Bang Camaro does its thing. That's because 19 (or so) singers are squeezed onto the stage, fighting for space, among the four musicians. It's classic hard-driving hard rock, with definite sex appeal. We mean they're a "boy" band consisting of "men," and they were featured last year in Playgirl. (No, not nekkid - there was a story about 'em.) They're at the Hard Rock Cafe Saturday April 5 for a show benefiting Ernie Boch Jr.'s Music Drives Us Foundation. There's a $50 VIP reception at 7 p.m.; if you want just the show, that starts at 9 p.m. and will run you $20. Bang your head.
