How did this thread go on so long without anyone mentioning Ministry?
Thieves, Stigmata, So what, Just one fix, The Missing, New World Order, Breathe, Psalm 69, Burning Inside... All by Ministry, and all kick ass beyond belief. Might make you slap the shit out of the first person that sweats all over the bench and doesn't wipe it off.
Also Nine inch nails and Front line assembly. If you are really whacked out, "In the hall of the Mountain King", by Grieg.
...and lets not forget Marilyn Manson.
