Back in May Sigur Ros announced that for their latest outing - the woozy, dreamlike Valtari - they would provide a dozen filmmakers with a small budget and give them carte blanche to make what they would of the album.

Cut to September and they've just released the 9th video in the Mystery Film Experiment, entitled "Seraph", and it could be the best one yet.

The work of graphic novelist Dash Shaw and Hedwig and the Angry Inch director John Cameron Mitchell, "Seraph" takes album tracks "Rembihnútur" and "Ekki Múkk" and transforms them into a provocative, wrenching parable about religion, bodily transgression, sin and the fall of man. Which also includes a fair amount of crudely drawn nudity. It's... weird, but oh so worth it.

Five more videos are due to be released, with the project wrapping up on November 19. You can find the rest of the films here.
