Mumford & Sons Debuts 'The Wolf,' New Song Off Banjo-less Album

Mumford & Sons will release their first "rock" album on May 4 , but the band debuted its second track, "The Wolf," on Thursday. Paired with a city-scape visualizer similar to the one released with the album's first song, "Believe," it's heavy on guitar, and sounds less like Coldplay, more like Foo Fighters.
