Think of a deranged mixture of The Dresden Dolls and Tori Amos. For some reason she seems to have quite a large goth following (but then I guess so do the aforementioned artists...) and certainly lists a whole load of goth and industrial bands as influences on her work.
She's also incredibly cute - but don't let that influence your enjoyment of her music which is fantastic regardless :p
Emilie Autum Website
Emilie Autumn Myspace
From her Myspace page: "Combine the violin mastery of Nigel Kennedy, the voice of an alien Siouxsie/Bowie hybrid, and the looks of a post-apocalyptic Marie Antoinette, and what do you get? Emilie Autumn. The pink-haired princess of "victoriandustrial" has already morphed her way from classically trained violin prodigy to extreme rock performer with the ability to shred on a fiddle à la Yngwie, and with a cult following to match."
