What do Aidan Gillen (Tommy Carcetti from vaunted TV show The Wire), a talking snail, and a fox have in common? Not much before the release of “Ekki Múkk,” the latest video in Sigur Rós’s ongoing Mystery Film Experiment. Gillen plays a man, guided by a talking snail, who stumbles upon an injured fox and attempts to rescue it. The result is quintessential Sigur Rós, equal parts beauty and grotesquerie–a fitting accompaniment for the band’s typical melancholic grandeur. Although there is no naked Shia LaBeouf this time (sorry ladies), “Ekki Múkk,” proves to be one of the more moving videos in the series.
