Mumford & Sons are a British folk rock band. The band consists of Marcus Mumford (lead vocals, guitar, drums, mandolin), Ben Lovett (vocals, keyboards, accordion, drums), Winston Marshall (vocals, banjo, guitar, resonator guitar, dobro), and Ted Dwane (vocals, string bass, drums, guitar). Mumford & Sons were formed in December 2007, emerging from West London with such artists as Laura Marling, Johnny Flynn and Noah and the Whale.

Mumford & Sons recorded an EP, "Love Your Ground", and performed in small to medium-sized venues in the UK and the United States playing to new audiences and raising interest for a forthcoming album. Their debut album, Sigh No More, was released in the UK and Ireland in October 2009, and February 2010 in the US. The album reached number one in Ireland, Australia and New Zealand, and eventually peaked at number two on the UK Albums Chart and the Billboard 200 in the US. The band gained popularity throughout 2010, performing for larger audiences and making their first network television appearances in the US. On 1 December 2010, the band received two Grammy Award nominations, one for Best New Artist and the other for Best Rock Song ("Little Lion Man"). The ensuing live performance at the Grammy ceremony in February 2011 led to an increased airplay and popularity for singles from Sigh No More. The band won the ARIA Music Award for Most Popular International Artist in 2010, and the Brit Award in 2011 for Best British Album.
