This piece is part of the program Die Musikwerkstatt and was transmitted on the 11^th of November 1964 by the GDR’s radio station Radio DDR 2. The program contains a dialogue between Dieter Boeck and Gerhard Steinke, the latter being the director of the Labor für Akustisch-Musikalische Grenzprobleme and sound engineer inside the Funkhaus in Nalepastraße, the central broadcasting house of the GDR. In this episode, Steinke discusses the entangled influences between technique and art, providing precise recorded examples of the acoustic characteristics of the Funkhaus in Nalepastraße. It is one of the best examples in which the sonic-spatial characteristics of a building are explained and transmitted to a broader audience, making evident the relevance of the pedagogical aspect and the political ambition behind the sonic project broadcast by the GDR.
