Query: INSANE ELECTRONIC MASTERPIECE.

Ikue Mori is some sort of genius, and this album is one of her greatest creations. She uses her unique, modified drum machines to create some of the most alien, f'ed up electronic music you're likely to find. Completely weird, yet mystical and rewarding. Ikue Mori is one of my favorite artists, so i am utterly biased, but this is VERY HIGHLY RECOMMENDED stuff, baby.
