The only one of those I ever got into was Aphex Twin, but alot of my friends listen to many of those bands and others of that sort.
Psychostick - Fake My Own Death And Go Platinum
Disturbed - Forgiven
White Zombie - Thunderkiss '65
Lamb Of God - Choke Sermon
Otep - Unveiled
Strapping Young Lad - You Suck
Kiss - I Love It Loud
Behemoth - Defiling Morality Ov Black God
Strapping Young Lad - We Ride
Valient Thorr - 1000 Winters In A Row
Why does it seem like the same artists always come up?
Anyway, there's some good ones on that list.
