"I held so much anger in me for so many years until I finally graduated from high school, started partying a lot more and raging on the music," says Hanna. "And that is what Purple is all about. You don't know how many times I've heard 'Hey, you drum pretty good�for a girl'.

"It's that phrase: 'for a girl'. It doesn't make me mad though; it's funny. It just makes me want to be more bad-ass than the boys. Anger can be extremely inspiring that way."
