Mumford & Sons already had a certain amount of popularity in their native England, as well as the rest of the British Isles, Australia, and New Zealand, before their full-length debut, Sigh No More, came out in the US, courtesy of Glassnote Records. And it is, upon first listen, easy to see why. Pulling very directly from their influences – Fairport Convention, The Strawbs, and, most contemporarily, The Frames – Mumford & Sons write overwrought but inarguably catchy songs that shift between rollicking banjos, and four-part harmonies, and the less-produced pieces focusing more on Marcus Mumford’s (unfortunately, the other members are not his actual sons) pained vocals.
