This piece is part of the program Auf dem Weg zu einer neuen Klangkunst and was transmitted on the 10^th of August 1965 by the GDR’s radio station Deutschlandsender. This episode is part of a series dedicated to the history of electronic music in different countries. Following three other episodes monographically dedicated to the studios in Paris (Groupe de Recherches Musicales), Cologne (Studio für elektronische Musik), and Munich (Siemens Studio für Elektronische Musik), this program was dedicated to the developments of electronic music in socialist countries, with a particular focus on the experimental studio in Warsaw, Poland. After providing an overview of work developed in socialist countries, including studios in Prague, Bratislava, and Pilsen in the Czech Republic, some examples from the Soviet Union, and others from Hungary, the program focuses on the experiments done with tape in the studio in Poland. Steinke makes specific remarks about the “architectonic dimensions” of this studio, designed by architect and Team 10 member Oskar Hansen.
