Just a week after Mumford and Sons announced their new album [1], Wilder Mind, the band has released their first single, "Believe." If you're expecting to hear a whole lot of fiddle, well, you're in for a surprise, because the song takes their sound in a new direction. Don't worry, though — Marcus Mumford's vocals are still front and center, and as with many of their songs, there's a natural buildup. Listen to the single, then weigh in: Are you into Mumford & Sons' new sound?
