It’s been a pretty agonizing couple of years for Sigur Rós fans. In early 2010, the Icelandic art-rockers announced a double bummer: They were scrapping the recordings that were supposed to make up their sixth studio album, then going on an indefinite hiatus. The group’s eternally elfin lead singer Jonsi recently hinted that new material will be on its way sometime soon, but until then, fans have the new concert doc inni to tide them over. Canadian filmmaker Vincent Morisset (who also directed Arcade Fire’s film Mirror Noir) shot Sigur Rós’ last performance at London’s Alexandria Palace in a dreamy, impressionistic style that suits the band’s emotive sound. Unlike the more narrative-based 2007 Sigur Rós documentary Heima, inni focuses singularly on the band’s transcendent live show. It was just released as a DVD and live album, but it’s better witnessed on a screen as big and panoramic as the band’s sound. The film shows at 7:15 p.m. and 9 p.m. at AFI Silver Theatre, 8633 Colesville Rd., Silver Spring. $11. afi.com/silver. (301) 495-6720.
