Re: Female Rock Voices.
Anne Beeche from The Jackets.
No, I'm just kidding. I know she's already been said, but ANN WILSON FROM HEART. Seriously. It's one of the best female voices ever.
That choir soprano guest from the last song on Evanescence's Fallen was good, too. (Souned opera-ish, stood out) She was the best part of their entire discography.
