Will Butler (of Arcade Fire/being Win Butler's little brother fame) released his first solo album, Policy, earlier this year. Although "Anna," the second single off the album, already has a video, Butler decided to release one that emphasizes how danceable the track is. The new video features choreography by Ryan Heffington, the brains behind Sia's brilliant "Chandelier" video, and a cameo by Emma Stone. Stone and a group of sailors are seen dancing a theatric number aboard the RMS Queen Mary, currently anchored in Long Island. Butler confirmed that the video was inspired by the legend of the Lady in White, a dancing ghost who apparently haunts the Queen Mary.
