The concept behind the video for Feist‘s “Bittersweet Melodies” is pretty interesting. Utilizing Argentinian photographer Irina Werning’s photos from her Back to the Future series, old photographs of the subjects are placed next to photographs of the subjects in identical poses as adults. Some of them are quite funny as in some of the baby versions, you simply can’t tell what sex the child is until you look at the photograph right beside it. It makes for a good game of “Guess Their Sex.”

In related news, the artwork for Feist and Mastodon‘s upcoming split record for Record Store Day, also known as Feistodon, has been released. And it is scary. Check it out below the video.
