The seminal electronic trio's third album, Zeit, along with all of Tangerine Dream's early material, had a major effect on the direction of Krautrock. A double album made up of just four tracks, Zeit (named for the German word for "time") is conceptually based on the idea that time does not actually exist outside our minds, or something weird like that. The sound is closer to the rock-based ambient music of Neu! and Popol Vuh than the New Age label they were saddled with in the later '70s and '80s. Just the cellos that open the album are essential listening for any Godspeed! You Black Emperor fan.
