Good call on that one. And since we've mentioned a couple of the heavier bands, we may as well mention Kittie.
Oh crap! I have both Otep and Kittie on my iPod. Ridiculous, especially since Kittie is an all-girls band. We're slippin', guy.
She does some here and there, but she doesn't do lead and she's not on every song. I think the most she's done was on Rebirthing.
