I'll start. For me it's a toss up between pantera - vulgar display of power or mastodon - the hunter. whats yours?
VdoP - good one! Depends on the workout of course, and I usually do a mix/playlist, but for albums I would go with: Master of Puppets - Metallica Thornography - Cradle of Filth Fat of the Land - The Prodigy Subliminal Verses - Slipknot When I teach my boxing class I always finish with "Raining Blood" by Slayer to get the juices flowing!
