What Is The Most Violent And Rude Genre Of Rock Music?

Let me give you guys a little help, hands down no contest it's brutal death metal. Nothing else even comes close. Just check groups like Lust Of Decay, Devourment, Gorgasm, Cannibal Corpse, Dying Fetus, Aversion To Life, Necrotic Disgorgement and you'll see. All those other bands are wuss when compared to.

Death Metal:)

I would have to say Alice Cooper, unless you are talking all Rock music, then I would have to say Marilyn Manson

I'd say that you should try Dragonforce. I'm not sure what fast and rude tones are but they're a really good band.
