Mumford & Sons totally threw down at Stubb's on 11.3.10, and Roxwel was super lucky to score an interview with Ted  and Ben before they took the stage and film the beginning of the sold out show.

What's so ironic is that Mumford & Sons only released their debut album, Sigh No More, in the U.S. earlier this year...and they're selling out EVERYWHERE.  What's their secret to achieving such phenomenal success?

"We've just been touring constantly, and things have grown faster than we anticipated," says Ted. 

I'll say!  These guys are such humble and talented musicians that are truly in this for their love of music, which spans country & bluegrass (Winston), folk (Marcus), blues (Ted) and jazz (Ben).  And according to Ben, it was Winston who lead the band in a bluegrassy direction since it's conducive to having fun and dancing, as well as its acoustic nature. 

What's next for Mumford & Sons?  Well, watch the interview to find out!  Also, be sure to check out the live footage - featuring "Sigh No More," "Roll Away Your Stone" and "Winter Winds" - as well as a blog post and photos from the show.
