Definitely not everyone's cup of tea, but with the release of Warhammer: Age of Reckoning - the new MMO kid on the block - I thought we needed some musical references. This is from Bolt Thrower, which at one point actually was sponsored by Games Workshop (the guys behind the Warhammer universe(s)). This was one of the few tracks with actual footage I could find.

"Bolt Thrower are an English death metal band from Coventry, England. They formed in 1986 and released their first album with Vinyl Solution in 1988. The band then shifted to a new record label, Earache Records, soon becoming one of the best selling bands on that label. "

Oh, and female bass player! :)
