Brattle showing Sigur Ros concert films ‘Heima’ and ‘Inni’ ahead of Boston Calling

Back in the day, we all used to prepare for a Sigur Ros concert by taking a bunch of drugs and renting a mini bus. But these days, the drugs don’t work (Ashcroft!) and we just can’t up and leave to follow our favorite Icelandic band around North America. We have families. Commitments. Jobs.

Enter Cambridge’s Brattle Theatre to the rescue, which preps us for Sigur Ros’ set at Boston Calling by screening the band’s two concert films, 2007’s Heima and 2011’s Inni, on Thursday (May 25). Heima, which “follows the band as they perform a series of unannounced shows throughout their native country of Iceland,” shows at 7:30 p.m., while Inni, an experimental film that “focuses purely on Sigur Rós in concert using footage from live performances re-shot on 16mm film through prisms and other found objects,” follows at 9:30 p.m.

That will give us all less than 24 hours before Sigur Ros take the Boston Calling stage at 9:20 p.m. on Friday night. The screening doesn’t solve the massive conundrum of Sigur Ros performing at the same time as Chance The Rapper on the festival’s stocked opening slate (Mac Demarco, Solange, Bon Iver, Sylvan Esso and others perform earlier), but it will get us in the proper mindset.

Watch the trailers for both films below, and peep Boston Calling’s full lineup after the jump.
