Bjork is really freaking talented. Sure, it's easy to be turned off by her utter STRANGENESS, but wow, what music. Her performance in "Dancer in the Dark" is also one of the best things I've ever, ever, ever seen.
If you're interested in checking out her music, you should of course start with "Debut." Great tunes. Also, her latest, "Verspertine," is minimalist, but it grows with each listen. Takes some patience, but it will one day just click.
Anyway, a Bjork game soundtrack for PN03 would be very interesting...hahaha...
