Bon Iver main man Justin Vernon has revealed details of a rumoured collaboration with Kanye West. It had already been reported that Kanye flew to Hawaii to work with Vernon and that he intended to sample one of Bon Iver's songs. Now, Vernon told Pitchfork.com that he recorded vocals for "at least ten songs" with West.

Vernon and West actually made three separate trips to Hawaii this year and Kanye is expected to include one song in particular on his upcoming album, and may even make it his next single. The track in question, 'Lost in The World', samples the Bon Iver song 'Woods', which is already heavily Auto-Tuned.

"That whole first week I was there we worked on the 'Woods' song, which is called 'Lost In The World'. We were just eating breakfast and listening to the song on the speakers and he's like, 'Fuck, this is going to be the festival closer', I was like, 'Yeah, cool'. It kind of freaked me out."

Speaking of the rest of their sessions, Vernon added, "It was the same kind of thing, throwing ideas around. There are a bunch of other songs I'd just throw down on, write a little hook, whatever. In the studio, he was referencing Trent Reznor, Al Green, The Roots, the fucking awesomest shit. It made total sense to me."

"I was literally in the back room rolling a spliff with Rick Ross talking about what to do on the next part of a song. It was astonishing. Kanye came back and was like, 'Look at you two guys. This is the craziest studio in the Western world right now!'".

Kanye's still untitled fifth album is due for release on November 12th. You can download a collaboration with Beyonce and Charlie Wilson via www.kanyeuniversecity.com.
