Punk/rock Bedroom makeover-ideas?

Question:I'm redoing my bedroom. I have white walls and i hate them, but can't paint over them. I have a corner desk, dresser, bed, and 3 night stands. I have the layout done. But bedding is going to be black and redplaid (Sorta kinda like the mosh pit from wakeupfrankie.com). I'm don't want the tready stuff. And i'm not trying to be a poser. But, punk/rock is the only way i can fingure out how to call what kind of theme i want for my room. I have a few ideas, not many. Can anyone help me? Please?
