Author: Leonardo DiCaprio. A 2007 documentary about how human carelessness has been harming the environment, THE 11TH HOUR features a soundtrack of appropriately atmospheric and sweeping songs. While the Icelandic post-rock ensemble Sigur Ros appears twice (see the melancholy "Sigur 3" and the majestic "Svefn G Englar"), the collection also includes tracks by the band's contemporaries (Mogwai's sprawling "Mogwai Fear Satan") and influences (Cocteau Twins' elegant "Otterley"), making for a dreamy and emotive mix.
