On Bill & Ted's DVD Extra with Bjorn and Rockness, JoBlo.com had this to say:

"Air Guitar Tutorial with Champs The Rockness Monster and Bjorn Turoque (13 minutes):

Air guitar Champs? I guess there really is something for everyone but this was kinda weird. Rockness Monster actually looks like he’s having some fun with this but the Turoque character is just bizarre although hilarious. The two guys discuss their own techniques and share their top ten tips to playing the air guitar."

Maybe he actually is getting too old for this...?
