With competitive air guitar bigger than ever, we look forward to the days when an entire generation has been weaned on this balls-out, picks-down celebration of rocking hard without ever practicing a lick. Of course, the aerial combat is brutal enough with the scene's current crop of superstars like C-Diddy, Big Rig, and Hot Lixx. Show support for your local axeless heroes at this weekend's two SF Regional Championships: the Golden Gate Regional, tonight, and the Bay Bridge Regional tomorrow night.
