The AV Club has been doing their AV: Undercover project for a few years now with some really great results. You can see most of them here. Basically they invite bands to the Little Round Room in their office and have them choose from a list of songs to cover. Thankfully Gwar chose the Kansas classic "Carry On My Wayward Son" and tore it a new asshole. You can check out the video below. Amazingly they were able to fit all of the Antarcticans into that small space(including the giant penises)
Yes Oderus, I agree. "Sheer Brilliance!" You can see Gwar as part of Rock And Shock at The Palladium and DCU Center in Worcester. MA this weekend. If you do see Gwar watch out for the flying fluids and goo. Get a full listing of guests and events here.
