Bon Iver and James Blake are set to collaborate on a new project entitled ‘Fall Creek Boys Choir’.

Blake announced the news on his Twitter account, though no more details about what kind of project the duo will undertake has been released.

The tweet simply reads: “24th August 2011 – James Blake & Bon Iver 'Fall Creek Boys Choir’”.

However, Fall Creek is the name of the town in which Justin Vernon of Bon Iver owns a studio.

Bon Iver recently the music video for new single 'Holocene'. The video was shot on location in Iceland and was directed by Nabil Elderkin.

Says Elderkin of the video: "That place is the most magical place in the world, it looked like Mars to me, so I always wanted to shoot there.” The 12” version of the single is released on September 5.

Bon Iver are set to embark on their biggest sold-out UK tour this October.
