Angela Gossow from Arch Enemy
By the way, can people start making sure they list who the singer is and if they're from a band, which band that is?
Angela definitely... But I have to say when I saw her live, I really believed that she can make those sounds...
Another one that surprised me is Ambrosia Parsley from Shivaree... Listening to their lovely song "Goodnight Moon" I always imagined her mini mini tiny blonde chick... she wasn't....
EDIT: just remembered another one...
Michael Poulsen from Volbeat.... even watching them live didn't help... howcome that boy has that voice?
