A part of the series "Experimental Electronic Underground GDR. On the evening of 3.9.1986, the privately announced and illegal concert took place in the Erloeserkirche in East Berlin/GDR. Montgomery mixed Schnitzler's music live from the tapes. Joerg Thomasius recorded the performance and released the recording in 1987 on his own underground cassette label Kroetenkassetten. 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 Joerg Thomasius' and Ken Gen Montgomery's written memories of this very special evening.
