Metallica (their old shit anyways), Megadeth, Slayer, Pantera, Mastodon, Lamb of God, Nile, Necrophagist, Cannibal Corpse, Behemoth, Arch Enemy, Opeth, Psychroptic, BLS, Ozzy, Black Sabbath, Decapitated, Dying Fetus, Exodus, Iron Maiden, Nevermore (Jeff Loomis = God), Sleep Terror, Strapping Young Lad, Vader, Dream Theater, GWAR.. some of their music but their show is crazy.

I also went to summer slaughter last summer, it was badass, cattle decapitation singer was hilarious and decapitated and necrophagist were fucking amazing. Marco Minnemens drum solo was insane. :jointsmile:
