Marduk and Crazy Town
Just imagine the fans...all the "soooo hardcore and evil and metal" kiddies that came for Crazy Town...crying for their mommas and peeing their pants during "Bleached Bones" and all the black/death metallers laughing their asses off about them...
Same thing goes for "Six Feet Under and Papa Roach", and "Cannibal Corpse and Limp Dickshit", "Bolt Thrower and Linkin Park" etc
