Bon Iver Collaborating With Alicia Keys On New Project

Bon Iver's Justin Vernon has revealed that he's planning to collaborate with Alicia Keys.

The singer, who released the band's self-titled second studio album last year, said he was planning on working on other projects away from Bon Iver,

In an interview with USA Today: "I have a big idea to do an American songbook of the greatest women singers,"

He added. "There are so many: Casey (Dienel) from White Hinterland, Bonnie Raitt, Alicia."

Vernon also said that thath he might not release another album for five years.

''I don't have any songs written yet. I'm guessing three years. But it could be five. It could be only one more. It just depends when the songs come about. I sort of have to wait till they reveal themselves. ''
