You don't even need a guitar to let your hot licks hang out anymore. Duckwalk like Angus (Young; AC/DC), windmill like (Pete; The Who) Townshend and bow like (Jimmy; Led Zeppelin) Page -- no prob; all with air, but not like (Michael; Nike Air) Jordan.
Air guitar is no longer for the guys without girlfriends, stuck at home with nothing but cassettes and the bathroom mirror to fill a Saturday night. Heck, it's not even just for guys.
