The opening track from Björk's upcoming seventh studio album, Biophilia, has surfaced and it's very different to what we've heard so far ('Crystalline', 'Cosmogony', 'Virus').

The track is called 'Moon' and it features layered vocals sat alongside beautiful (and subtle) instrumentation. It might not exactly be the hit in the face you'd expect from an album opener, but it's pretty stunning nonetheless.

Biophilia hits the shelves on September 27th.
