The best fucking example of fucking German fucking thrash 'till fucking death. They had different periods, but none of them was bad. And the fuck, if you're new to Kreator, here's a few songs you MUST listen to: Flag of Hate, Extreme Aggression, Renewal, Violent Revolution, Enemy of God.
And god, get lost with this death metal thing.
"Dude, I went to Kreator yesterday and it was fucking awesome."
"You went to the mosh?"
"Fuck yeah, Extreme Aggression murdered everything."
