Inni is Sigur Rós's second live film following 2007′s hugely-celebrated Heima. Whereas that film positioned the enigmatic group in the context of their Icelandic homeland, providing geographical, social, and historical perspectives on their otherworldly music, with uplifting results, Inni focusses purely on the band's performance. Interweaving archive material from the band's first ten years with the sometimes gossamer light, sometimes punishingly intense, concert footage, Inni is a persuasive account of one of the biggest rock bands of late.
