Doesn't that crisp new copy of 'Shields' look strangely at home in the hands of Jay Leno as he holds up at while introducing Grizzly Bear? New York magazine cover stars and everybody's favorite rock alter boys (except ours, apparently) hit the 'The Tonight Show With Jay Leno' stage last night (Oct. 11) to perform 'Speak in Rounds,' an intricate number from 'Shields' that starts slow but quickly gains momentum and ultimately comes across sublimely on TV (or computer), with new touring keyboardist Aaron Arntz giving a little extra jolt of energy to the proceedings.

Grizzly Bear head across the pond next week for a European vacation trek that will keep them on the road through a Nov. 5 gig in Amsterdam, the Netherlands, before heading to Australia. Check out their complete itinerary here.
