Though the various components repeat themselves incessantly, it’s how they interact and build that determines the sound — and that’s the essence of most electronic dance music, that complex interplay between several repetitive elements.
(The AMG on Manuel Göttsching’s E2-E4 which was recorded in 1981)
Formulated like this it seems to make sense. The repetition of the elements drum machine loop, guitar line and synth figure is not 100% linear. There is a dynamic operator fusing those three in the equation. But as can be heard in this small extract the variational element is too small to not bore the listener even after less than five minutes. This piece actually goes on for almost one hour. A torture for anybody who hasn’t taken the adequate drugs. The funny thing about this track is that it is actually by Manuel Göttsching who was in Ash Ra Tempel from Berlin, one of the early krautrock bands. They were electronic pioneers playing similar spherical music as Tangerine Dream. Klaus Schulze was even a member of Ash Ra Tempel. So in the end techno was just one little twig from a particular branch of the huge krautrock tree. And it became a German speciality again.
