No kidding: The U.S. Air Guitar Championships are among the most exciting live music events you'll see this year. The tour is raging across 21 cities, where would-be rockers put on a show of virtual shredding, where style and flash are totally more important than actual technique. Each competition consists of two rounds: In round one, you bang your head, throw up your devil horns, and generally rip it up to a song of your choice. In round two, you won't know what song you're performing to until the judges actually play it. And that, guitar hero, is what separates the men from the boys. And if that sounds like a full-on goof, you ain't seen nuthin' yet: This year's show features a live set by Tragedy, the world's finest metal tribute to the Bee Gees. They've got night fever, dude.
