Shadowy UK ambient producer The Haxan Cloak has revealed that he's been working with Björk on her album, joining the likes of Arca and (apparently) some names from PC Music.

There are almost no other details about the Icelandic artist's long-player.

I can now share, with equal parts humility and excitement, the last few months I've been working with @bjork on her new record. An honour.
