Mumford & Sons und Sierra Ferrell

Featuring Marcus Mumford (vocals, guitars, drums), Winston Marshall (vocals, banjo, dobro), Ben Lovett (vocals, keyboards) and Ted Dwae (vocals, bass), the band came together in 2007, soon becoming a recognized name in London's growing folk scene. Persitent performing and songwriting led to an appearance at 2008's Glastonbury Festival, gaining many new fans in the process. Shortly after, their self-titled debut EP was released, establishing their name in the indie rock scene.

Two more EPs followed, "Love Your Ground" (2008) and "Cave and the Open Sea" in 2009, attracting the interest of major label, Island Records, who were quick to sign the promising act to their roster. Working with Markus Dracs, producer of Arcade Fire and the Maccabees, Mumford & Sons started work on their debut album. Releasing the single "Little Lion Man," anticipation for their debut grew feverish, with the track being named 'Hottest Record in the World This Week' by BBC Radio 1 DJ, Zane Lowe. Mumford & Sons were then named part of BBC's 'Sound of 2009' poll, making them one of the most talked about acts in the UK at the time.

Their debut album, "Sigh No More," was released later that year, achieving commercial success. The following year, the album was issued in America, on Glassnote Records, finding further commercial success, selling a million copies. Yet it was with their second record, "Babel," that Mumford & Sons became international stars, with the album topping the Billboard Album Chart in the US in 2012, before then selling multi-Platinum. A live album, "Road to Red Rocks," recorded at Colorado's Red Rock amphitheater, was released shortly after that same year.

In 2013, Mumford & Sons were awarded with a Grammy Award for 'Best Album of the Year' with "Babel."Extensive touring followed, which saw the band headline many festivals across the globe, including Bonnaroo Music Festival and Glastonbury Festival. They then embarked on a hiatus, before returning to live performance in 2015, with the promise of a new album.
