This piece is part of the program Auf dem Weg zu einer neuen Klangkunst and was transmitted on the 16^th of October 1965 by the GDR’s radio station Deutschlandsender. The program is entirely dedicated to the history and experiments conducted at the Illinois Experimental Studio, founded by Lejaren Hiller in 1958. The discussion is between Gerhard Steinke and Gerhard Schwalbe, and it highlights the uniqueness of the computer-generated sounds by Hiller and his collaborators in this studio. The program makes specific references to the book Experimental Music (McGraw Hill, 1959), published by Hiller and Leonard Isaacson, and gives the listener insights into the exchanges and collaborations occurring between electronic music studios across the Cold War divide. Gerhard Steinke emphasizes that Hiller provided him with a mono copy of the sound pieces presented in the program, due to the impossibility of stereo radio transmission at that time.
