Not really sure about the impact of the "East/West thing" - competition for being part of the "acclaimed" group of pianists was fierce to say the least and furthermore Classical Music Labels started from the 70`s onwards looking much closer about marketing opportunities reg individual artists .... a similar faith to Rösel`s was the limited fame of the Suske Quartett, whose 70`s Mozart and Beethoven recordings (again originally released on Eterna) easily could withstand the competition of the best string ensembles of that time ....
