This documentary tells the story of Techno music as an underground movement, from its beginning until now. This film is mostly focused on Paris and Berlin and the foundation of a techno scene. Two different cities, two different tales, but techno grew up in both, from secret underground parties, to huge clubs, from a small faceless movement to an established business, and from vinyl to digital. (In French and English, with subtitles). After the screening, there will be a Q&A with Marc-Antoine Percier of the Alliance Française, about electronic music.
