Watch Voices (1972) Official Trailer

A nearly 30 minute long conversation in a living room party. Unlike in a regular TV play the jabber conversation can hardly be understood. Sometimes a line or two can be picked up. There's an intermezzo when Schippers alias Jacques Plafond comes to play one of his 'modern' piano pieces, to the disgust of the party's guests, whose chattering in the end isn't far removed from the piano play.
