This haunting and beautiful short film, which is much more than a music video, is for the Sigur Rós track Fjögur Píanó off their current album Valtari is directed by Alma Har'el and stars Shia LaBeouf and Denna Thomsen. The acclaimed Icelandic band Sigur Rós recently asked a dozen filmmakers to each choose a song from its new album, Valtari, and shoot a video inspired by the music as part of their Mystery Film Project. All the directors received the same $10,000 budget and zero instructions from the band.
