As part of our series "Experimental Electronic Underground GDR", we are very pleased to be able to make a very special recording available again. On the evening of 3.9.1986, the privately announced and illegal concert took place in the Erlöserkirche in East Berlin/GDR. Montgomery mixed Schnitzler's music live from the tapes. Jörg Thomasius recorded the performance and released the recording in 1987 on his own underground cassette label Krötenkassetten. The elaborately restored original recording is now being released for the first time on LP and CD under the title "CAS-CON II". In addition to photos and contemporary documents, it also includes Jörg Thomasius' and Ken Gen Montgomery's written memories of this very special evening.
