"Cosmogony" is a beautiful ballad that appears on Bjork's upcoming full-length album Biophilia, which is set to be released on Sep 26 via One Little Indian/Nonesuch. Despite her flair for the eccentric, "Cosmogony" soars due to its simplicity. It consists of not much more than Bjork emoting over a bed of swelling and pulsating horns and cymbals, and that's just fine. The Biophilia app comes out on iTunes tomorrow, July 19, and over time will feature interactive experiences tied to each of the album's ten tracks. Give "Cosmogony" a listen below.
