Byl jazz (1983)

 

 

Set in 1952, film tells the story of young musicians playing - then forbidden - jazz music in basements and attics around Poland. The group hires itself to social parties, youth dances, etc, each time waiting for the management to disappear in order to shift gears to hot music. The crowd either loves it or does not know what to do.

From memory:  Amiable and heart-felt depiction of the situation jazz music faced behind the Iron Curtain in the 1950s is characterized by excellent period detail, atmosphere and a good cast.
