Do you remember 2009’s Sigh No More? What about “Little Lion Man?” “The Cave?” Yeah, of course you do. As if you could forget Mumford & Sons so easily. Last year, the band brought us their follow up to Sigh No More, Babel. Songs like “I Will Wait,” “Hopeless Wanderer” and “Babel” brought back the band with the same lyrical power and rousing folk/bluegrass musicality that fans had come to expect from the band. The band has also gotten a good share of Grammy nominations, including Album of the Year, Best Rock Performance, Best Rock Song, Best Americana Album, Best Song Written for a Visual Medium and Best Long Form Music Video. So yeah. They’re kind of a big deal. Mumford & Sons will be playing  at the Barclays Center on February 12. And don’t forget to check them out at the Grammys on February 10.
