In 1982 Schnitzler had already met the New York musician Ken Gen Montgomery, who then regularly performed Schnitzlers' compositions live at various venues worldwide. And so Schnitzler also produced 4 cassettes especially for his concert in East Berlin, which were sent by courier from West to East Berlin. 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.
