What are some rocker inspired haircuts?

Im getting my hair cut and i have a rocker type looked (eg, skinnies, black , piercings, 1inch ears) and i want a change with my hair, its too boring. What are some cool rocker haircuts that're kinda like nikki sixx or the dude from tokio hotel or kat von d. Im a dude btw, but i want a really awesome edgy out there haircut, any suggestions?
