this is without a doubt the weirdest song on my iPod :D I honestly don't like it that much and along with Ancestors the worst song by Björk imo. Even though this isn't actually Björk singing. But other that that I find the whole DR9 album pretty interesting to listen to.
It's a really interesting song, but it's too exhaustive to listen to.  I always imagine a monk in a robe singing it, with a woodworker in the background shouting encouragement to him while hitting a plank.
