Good question. I came back from Kaye Mortley’s workshop in Phonurgia Nova in Arles in 2003, full of enthusiasm to make this documentary. I started the interviews in 2004. Unfortunately, Zdeněk Bouček, the original producer, as well as the „ladies“ died few years later. I kept thinking about the project and re-listening. When I listened to the recordings again in 2012 (there is about 20 hours of them and Barbara Kosíková will include them in the Rudné village archives), it seemed that I had an obligation to put the material together – as a thank you to the ladies and to everybody else who has helped me.
