Dark Tranquillity, on one of their albums, has a female vocalist back-up for a few songs. That won't do for the long term though...

I heard this wonderful band the other day, with a female lead singer and I coulda sworn she was male...nope. All I remember about it was that she had replaced their original singer who had busted his cords or something. I'll have to find it and report back.
