If you were one of the few fans lucky enough to make it inside Mumford and Sons' intimate club gig in New York City this past week, you've already heard all the songs from their upcoming, sea-changing album, Wilder Mind. Considering they made everyone check their cell phones at the door, there's no tangible evidence of that unique performance, which means the rest of us will have to make due with the visualizer they unveiled for "The Wolf."

The song leads this installment of Mandatory Music – one that also sees Bright Eyes' Conor Oberst return to his punk outfit Desaparecidos and yet another taste of the next effort from Florence and the Machine. Best of all, feel free to hang onto your phone the whole time.
