Mumford and Sons Rock Red Rocks in New Video Clip

Mumford and Sons' recent U.S. tour earned the band some of their live best reviews yet, and this live clip shows why. Filmed during their sold out Aug. 28-29 stand at the scenic Red Rock Amphitheatre in Morrison, Colo., the video captures the British quartet in front of a rabid audience tearing through a rousing rendition of 'I Will Wait,' the first single off their forthcoming sophomore album, 'Babel.' Mumford and Sons just completed a month-long U.S. trek that wound down with a Sept. 1 performance at the Aspen Jazz festival in Colorado and are next scheduled to tour Australia and New Zealand in October.
