Alison Goldfrapp's otherworldly vocal range

I'm a little obsessed with vocal range videos. Every once in a while I scour youtube for new ones and I'm always happy to see a somewhat under-appreciate singer of whom I've been a fan for a while.

Alison is a soprano with a pretty impressive chest voice (I'm an alto, and I don't go that deep). I think she's been sort of pigeonholed as a dance or pop singer, though musically and vocally she more than transcends that.
