To whitewhale1965.
Yes it was a communist state, but some people got attraction in western popular music through some radioprogrammes, or in dancing-locations, where the GDR-Discjockeys had the order to play their own music and some western-pop music.
If some people from the former GDR had family-members in Western-Germany, they got a little chance to get LPs, or Singles by West-artists as original records. But in the case that the STASI-members controlled the parcels, that was bad luck.
In the former Electronic-stores, where AMIGA-records had been sold, some priviligated persons got that records very easily, but the regular citizens need luck and patience to get such a record. If someone had that luck, many and many tape-copies made the round. That is also history.
I don't get it. East Germany was a communist country during the Cold War - maybe even more nefarious than the Soviet Union. I would never have imagined their citizens would have access to Pink Floyd, or many of the other artists on this label.
