Carey Mulligan and Marcus Mumford strolled arm in arm through the streets of NYC on Thursday. The duo usually call London home, but they are in the Big Apple as Marcus gears up for the release of his new album with Mumford & Sons. If their first single, "Believe," is any indication, the band is going with a slightly new sound for Wilder Mind, which comes out on May 4. They'll be hitting the road to promote the album at Bonaroo and with their short Gentleman of the Road tour including stops in Scotland, Colorado, and Iowa. Marcus's NYC visit hasn't been all about business though, since he met up with his pal Jake Gyllenhaal earlier this week.
