With their first EP, Love Your Ground, unleashed just four years ago, Mumford and Sons has already shared a stage with the likes of Bob Dylan, Dr. Dre, Mick Jagger, and Lady Gaga at the 53rd Annual Grammy Awards earlier this year. Consisting of Marcus Mumford, Ben Lovett, “Country” Winston Marshal, and Ted Dwane, this hybrid of bluegrass, folk, and rock birthed from the West London Folk scene in 2007 have a rustic sound stocked with vocal harmonies and a banjo flourish. Yes, we love our boy bands to be brawny, but there’s nothing better than a good bookworm. Beyond instrumental finesse and (as described by his Facebook fans) “a voice that can break the heart of a robot,” Marcus Mumford has got brains, too. Many lyrics of the Mumford and Sons are wracked with literary references, to Shakespeare and Steinbeck. This bibliophile even runs an online book club from the Mumford and Sons website.
