Bon Iver's Justin Vernon is keeping mighty busy. He appeared on Kanye West and Jay-Z's Watch The Throne, collaborated with James Blake, and, oh right, released a great new album this summer. That's not all he's been up to, though, as he's also been in the studio with folk artist Kathleen Edwards. Vernon produced both cuts on her forthcoming 7" single Wapusk and even provided backing vocals on the gorgeous title track. You don't have to listen too closely to hear his falsetto, either. Those coos and oooohs are unmistakable. And while hearing him on "Wapusk" is great and all, the spotlight remains on Edwards, a name we're going to be checking for from now on.
