Jack White is something of a supergroup floozy. The White Stripes front man already has a group newer than the Raconteurs — the Dead Weather — but it'll be tough to match the success of that first 2006 project with co-vocalist Brendan Benson and two members of garage rockers the Greenhornes. The Raconteurs' single "Steady, As She Goes" was a summer radio smash, and the album it's on, Broken Boy Soldiers, sold some 425,000 copies.
