With tribal drums that put "Love Lockdown" to shame, Björk's charity collaboration with Radiohead's Thom Yorke was finally revealed yesterday as it leaked on the internet. In the track, Yorke's moans and airy howls illuminate drummer Brian Chippendale's blazing beat, the product being a sound that is a far cry from the duo's previous collaboration on a track for Björk's Dancer in the Dark soundtrack. “Nattura,” which will see its official release on 10/20 through iTunes, was composed as a benefit for the Nattura organization, a non-profit which serves to help preserve the Icelandic environment.
