Call Sepultura nu-metal? Where have you been? Everyone DID call them nu-metal until Max fucked off to make another nu-metal band. For fuck sake, the guy doesn't even have enough strings on his guitar to play a solo, how much more nu-metal can he be?!
And Coal Chamber didn't "originate" nu-metal, if anyone can be blamed for it I'd vote for Sepultura on that piece of shite "Roots".
Machine Head were nu-metal since they dropped the soloing and started whining like girls. At least admit it to yourself that you're a nu-metal fan, instead of trying to persuade everyone else that Machine Head are some kind of brutal death metal band.
And that new album is even worse than nu-metal since it sounds like those "trendy" poofs you hear on MTV all day. And Trivium.
