The Lumineers will take center stage at the Grammy Awards on Sunday with a performance and a possible trophy. The group is up for two awards: best new artist and best Americana album for its 2012 release. Last year at this time, the relatively then-unknown band hadn't even released a full-length album yet. By the end of 2012, though, it was hard to escape the group's song, "Ho Hey." See photos of the group here, courtesy of Getty Images.
