"I don't give two splats of an old negro junkie's vomit for your politico-philosophical treatises, kiddies. I like noise. I like big-ass vicious noise that makes my head spin. I wanna feel it whipping through me like a fucking jolt. We're so dilapidated and crushed by our pathetic existence we need it like a fix."

-Steve Albini
