In a recent interview with USA Today regarding his four Grammy nominations, Bon Iver's Justin Vernon mentioned a few projects he has in the works. He said that he has collaborated on songs with Alicia Keys and is working on a new album with Volcano Choir, "for the Japanese market." He's also making music with another project called the Shouting Matches, which he described as "sort of a blues-gospel band."

Vernon also told USA Today, "I have a big idea to do an American songbook of the greatest women singers. There are so many: Casey (Dienel) from White Hinterland, Bonnie Raitt, Alicia," and that he'd like to make "a one-off charity album to have an excuse to work with a bunch of people that I'd choose to work with, all at once."

Vernon also noted that another Bon Iver album probably won't surface for about three years. "But it could be five," he said, "It just depends when the songs come about. I sort of have to wait 'til they reveal themselves."

Bon Iver performs this weekend on "Saturday Night Live". The Grammys, meanwhile, air February 12. Bon Iver is not scheduled to perform. Watch the video for "Holocene":
