Song help

I've been trying to find a clip of this somewhere but it's impossible. It was in the second episode, they were talking about that soundhouse where they played air guitar. they show some guys headbanging and a song with an awesome riff is playing, but I can't figure out what it is.

it's also in this video at 5:43 http://www.youtube.com/watch?v=uUDq8ajv2u0
(I don't know how to make it clickable)


anita! you liar! we'll set your hair on fire!
