Shia LaBeouf appeared naked in a music video "Fjogur Piano" for Icelandic band Sigur Ros, directed by filmmaker Alma Har'el.
In the video, the actor is shown opposite actress Denna Thomsen as a destructive couple, doing drugs dancing, trashing a bedroom, admiring butterflies and reviewing their scars and wounds. They are also chased by two bearded men, who give them glowing lollipops.
