Earlier this month, as part of the auxiliary programming related to its current Spectacle music video exhibition, downtown’s Contemporary Arts Center welcomed award-winning singer/songwriter Feist and music video director Martin de Thurah for a special screening and talk. This Friday, the CAC welcomes another music video auteur, Vincent Morisset, who will present a screening of the widely acclaimed black-and-white concert film featuring Icelandic Post Rock superstars Sigur Rós titled Inni. (Morisset also made the Sigur Rós film Heima.) The movie screens at 6:30 p.m., followed by a discussion with Morisset about the Sigur Rós projects, as well as his stunning video work, including Arcade Fire’s riveting “interactive” video, “Sprawl II.” 6:30 p.m. The screening and chat are free to attend with regular gallery admission ($7.50; free for members).
