For their latest project, Sigur Ros dove into the Disney vault and dug up none other than Shia LaBeouf, who stars in their new video, "Fjogur Piano". The clip, which is the latest installment in their "Mystery Film Experiment" series, features the actor donning a pink fur bolero, engaging in some serious interpretive dancing, and weeping while surrounded by preserved butterflies. Oh right, and he gets totally naked for a second (for real!). Directed by Alma Har'el, who also directed the band's previous videos for "Eg anda" and "Varud", it's quite the sight. Check out the clip below!
