As part of their on going 'Valtari Mystery Film Experiment', Sigur Rós have unveiled yet another visual and this time it's for "Ekki múkk". The video is directed by Nick Abrahams and stars Aidan Gillen who you may recognise from The Wire as Tommy Carcetti or more recently as Petyr 'Littlefinger' Baelish in another HBO smash, Game of Thrones. Whatever you may or may not recognise him from, he plays a great little role in the video that also stars a snail voiced by Shirley Collins. Yes, a snail. It makes for very interesting viewing and a very nice addition to the previous videos we've seen. Check it out after the jump.
