Well unknown to me. The story about my vinyls from the eastern european countries is as follows: During the times of the "Iron Curtain" I did send to some jazzfans from East Germany (DDR), Poland and Russia my used "western vinyls" when I got a new japanese or spanish edition.
They did send me then what was available overthere (not always to my personal taste) but during the time I have also some good ones pref. the eastern big band. Poland had always a very modern oriented jazz scene then.
Two good albums here too!
