British rockers Marcus Mumford, Ben Lovett, Ted Dwane and "Country" Winston Marshall make up the irresistible Mumford & Sons. After their debut album, Sigh No More, hit the U.S. in February 2010, the band garnered two Grammy nominations and delivered a powerhouse performance at the ceremony. Both critics and listeners have agreed that Mumford & Sons' plunky country-roots sound is an audible delight, no easy triumph.
