Here's a hell of a 'what if' scenario: what if Iggy Pop narrated a nature documentary wherein the animal essentially plays the part of Josh Brolin in the first part of No Country For Old Men?

Well, wonder no more. Casper Balslev's video for Alt-J's In Cold Blood starts off innocently enough. It's the intrepid, wily adventures of your average wood mouse, and it's beautifully shot and majestically paced like the best the BBC can offer - right up until the point where our cute little mousey pal scuttles over a still-fresh disembodied human hand and into the aftermath of what we can only assume was a deal gone very bad indeed.

As far as narrative left-turns go, this one is loaded with visual hooks and mysteries to unpack. But essentially the moral is clear: the dangers faced by the plucky mouse in the natural world, pale in comparison to the darkness perpetrated by humankind.
