Yesterday, we revealed that Justin Timberlake has been working on some new music with Marcus Mumford. And this week saw the release of Atoms for Peace—Thom Yorke's supergroup with Red Hot Chili Pepper's bassist, Flea. Also, it turns out Radiohead has made a few trips to Jack White's Third Man Records, so there's lots of potential in these artist collaborations. What's a dream artist collaboration of yours?
