I don't doubt she is doing all the singing but during the growls she seems to perform them extremely effortlessly. I would have expected a deep inhalation of breath and/or a little more exertion.
So my question: is she really that good or is there some processing going on? She just makes it look so easy...
EDIT: Got my answer. The recorded stuff is hugely effected (ok) but the live vids are overdubbed (
