This is an extract from a piece by sound artist, Joan Schuman.
It tells the story of a man and woman who conduct a relationship in complete silence - even though they don't have to.
Listen to the full version and other work on her website: www.joanschuman.com
("Silence" is in the section, 'Speech Acts')
If you're interested in sound art and documentary combined, you might like John Wynne's work.

Both these pieces are featured on the Third Coast Festival site in Chicago. It's a fantastic place to explore documentary radio.
