Tangerine Dream - Signals from the Schwäbischen Strasse.

German TV film, also shown on Spanish TV in 1976, this is a film all about TD which includes informal interviews and concert/studio footage, most of which seems to have been done exclusively for the film. The interviews are in the German language. The street name in the title refers to where Edgar Froese used to live in Berlin (apparently Klaus Schulze lived on the same street at the time) and is now the site of the TDI offices.
