Air Guitar Nation

Not only is there a national air guitar championship, there's also a pretty great documentary about its birth and the hardcore instrument-less rockers who come to compete. Air Guitar Nation ($19) chronicles the first US Air Guitar Championships, following the top contestants, David "C. Diddy" Jung and Dan "Bjorn Turoque." The DVD includes an hour of bonuses, including behind-scenes-footage, deleted scenes, and additional air guitar performances.
