Fall Creek Boys Choir - James Blake vs. Justin Vernon [watch]

James Blake twittered only 5 days ago, something about him and Justin Vernon, master mind of Bon Iver, entitled Fall Creek Boys Choir.
Now they come up with their premier song entitled as above on BBC Radio 1.
It sounds as if those two experienced a lot with Autotune and vocal layers.
Leaves us with more suspicion and Enough Thunder to come in October of this year.
What will it be? We'll soon see.
