A film by Bettina Ehrhard for ZDF from 2020.
From the advertising text: The zero hour struck in 1945 for music too: New sounds should make Germans better Germans, according to the Allied plan. But with the Cold War came ideological appropriation – on both sides. In the documentary, a little illuminated chapter of German-German history is told in an entertaining way.
Music by Hanns Eisler can be heard. Talking about him and his work in the film: Daniel Pozner, Nuria Schönberg-Nono and Friederike Wißmann.
