Mumford & Sons is a folk rock band that was formed in London in 2007. The band currently consists of lead singer/guitarist Marcus Mumford, banjoist Winston Marshall, keyboardist/accordionist Ben Lovett and double bassist Ted Dwane. In addition to their main instruments, the members also tend to play several other instruments during live performances. Mumford & Sons released their first studio album, "Sigh No More", in October 2009. The album received great reviews from the music critics, which has helped the album sell over four million copies in the United States and United Kingdom combined. Despite the great sales, "Sigh No More", would only reach #2 on the UK and US music charts. After the release of "Sigh No More", Mumford & Sons went from playing small clubs to large theaters. The band would spend the next two years extensively touring the world in support of the first album. After the long touring schedule, Mumford & Sons would release their second album, "Babel", in September 2012, which would debut at number 1 on the UK and US charts. It would also go on to sell just under 5.5 million copies throughout the world. Mumford & Sons have received 12 Grammy nominations in their career, winning two ("Babel" won Album of the Year at the 2013 Grammy Awards. The band would also win Best Long Form Music Video for the song "Big Easy Express" in the same year). Mumford & Sons are currently working on their third studio album that is set to be released in 2015.
