Random Goth Clockwork Dance Performance

Glancing through my BoingBoing feed I came across a post about a rather peculiar slash interesting dance performance from Gothla, which is some sort of gothic bellydance event...

Besides the inventive choreography and costume, what I found interesting about this was the music. At approximately the 4:40 mark there's a real song with lyrics in there. I thought it sounded an awful lot like Joanna Newsom, so in my search for something Newsom to show off here for comparison, I actually found the exact song, Peach Plum Pear, featured in the Clockwork Couture performance.
