Watch: Sigur Rós Performs "Festival" From Live Album / Film "INNI"

Icelandic post-punk titans Sigur Rós have been rocking faces off for over ten years now, and their next project promises to continue that tradition. INNI, a double live album AND film, captures the band's last trip to London's Alexandria Palace, and judging by the first look at their performance of "Festival," is going to be totally fucking epic.

Check it out the live footage below in all of its stylized, film-noir goodness via NPR, and continue waiting impatiently for INNI's release on November 15.
