The YouTube Music Awards took place yesterday and it involved the creation of music videos, directed live at the event at Pier 36 in New York. Arcade Fire kicked it off with a performance of "Afterlife" from their new album Reflektor.

The video was directed by Spike Jonze, and features actress Greta Gerwig dancing her way in her apartment kitchen to the front of the stage with a group of girls in tow. Check it out after the jump:
