Pgm 409

Johannes Schmoelling made his first public appearance as a member of Tangerine Dream during their January 31st, 1980 concerts at the 'Palast der Republik' in the former East Berlin, particularly notable since TD was the first Western "rock" band allowed by the Communist government to perform there. The few tickets made available to the general public had been changing hands on the black market for up to two months' wages.

Six years after its initial release, in April 1986, the album was made available to the rest of the world by Virgin both on vinyl and CD. It was now titled Pergamon (after the impressive museum in East Berlin) and featured a completely different cover.
