Grizzly Bear's Ed Droste seemed genuinely bummed by his band's recent Grammy nomination snub -- and rightfully so, considering all the praise their 'Sheilds' album has garnered -- but he's not letting it keep him down. Droste and the Bear boys hit the stage of 'The Late Show With David Letterman' last night (Dec. 12) to bust out 'Shields' single 'Yet Again,' and the tight performance may have given the Grammy noms committee pause. (Watch it below.)

The Bear are no strangers to 'Letterman,' having appeared on the show at least two other times to perform 'Two Weeks' and 'Ready, Able,' both from 2009's 'Veckatimest.' They have one more 2012 gig on their itinerary -- a hometown New York show Friday night with Sleigh Bells -- and a slew of overseas dates lined up in 2013, starting off Jan. 31 in Mexico City. Check out their full schedule here.
