god damnit Halestorm and In This Moment were my first 2 ideas as well. Another obvious is Paramore but that might be too poppy, I'm talking first 2 albums the rest were shit. I'm not real big on female rock vocalists unless they are REALLY good. There is one band that is completely obscure that I listened to back in the day and I can't recall the name of course. I'm sure I have them somewhere in my Itunes but don't feel like searching through 15,000 songs right now. They were on a Burnout racing game soundtrack too
