Mumford & Sons' US debut album Sigh No More was released to critical acclaim, with glowing reviews from The New York Times and others. The album entered the Billboard Heatseekers chart at number two in its first week. The band recently played to sold-out crowds in New York City and Los Angeles, and made their first TV appearances, on The Late Show with David Letterman and The Late Late Show with Craig Ferguson.

Mumford & Sons' gutsy, banjo-driven, old-time sound marries the magic of Crosby, Stills & Nash with the might of Kings of Leon and harmonies Brian Wilson would be proud of . Sigh No More was recently released in the UK to critical accolades. The album debuted in the UK iTunes Top 10 and is being lauded by tastemaker publications such as NME ("A band who know they're onto something not just good, but spectacular") and Q Magazine ("A record that swings from arresting fragility to hearty dynamics.") The album was recorded at Eastcote Studios, where Arctic Monkeys, Brian Eno, Tindersticks and Laura Marling all honed their sound. The band teamed with producer Markus Dravs who has worked with such acts as Arcade Fire, Bjork and Peter Gabriel.
