Vintage Berlin School tracks typically ran about twenty or thirty minutes, filling one side of a vinyl LP. The genre was so thoroughly identified with the long form that a general shift to shorter pieces in the 1980s seemed to herald the death of the movement. After the coming of the compact disc "retro" artists were no longer limited by the need to flip over a vinyl record. Some newer works run continuously as a single track for almost 80 minutes.
An outgrowth of Krautrock, Berlin School was so named because most of its early practitioners were based out of Berlin, Germany. The genre's identification with space music made it distinct from the more percussive and rhythm-oriented Düsseldorf School which included Can, Cluster, Kraftwerk, and Neu!.
Berlin School was and still is a relatively self-contained style that has not had nearly the impact on music in general that Kraftwerk has had on synth pop and techno, but ambient, electronica, New Age, and trance are partially rooted in Berlin School. The genre is sometimes considered a sub-branch of New Age or ambient, though it predates the widespread usage of both terms.
