Sigur Ros made their return (kind of) this year with the release of INNI, a live album/film featuring a recording of a London concert in late 2008. And as a means of tossing a holiday present their fans' way, the Icelandic band is giving away a free download of one of the album's tracks. It's the lulling an INNI-exclusive "Lúppulagið," which we heard previously when it leaked to the web in early November. But now, Sigur Ros is letting you have it for the cost of a few mouse clicks. Well, they are just as long as their website stops crashing. You can stream the track below and download it here.
