Liked Greta's goofy moves in summer indie flick fave Frances Ha? Then you'll love her dance-like-no-one's-watching sequence in Arcade Fire's music video for Afterlife, which just happened to be filmed live at this weekend's YouTube Awards and was directed by Spike Jonze, naturally. It's all jazz hands, hair swooshing and fist pump—and it's guaranteed to put you in a good mood, even on an early Tuesday morning'. Work it, GG!
