Paul Dessau (1894-1979) has been a violin prodigy, became Otto Klemperer’s assistant and finally an accomplished conductor. He wrote operetta and film music – from mountain films with Leni Riefenstahl by director Arnold Fanck to Walt Disney’s animated films. Born in Hamburg, he was a soldier in World War I and a Jewish exile in France and the USA in WWII. In Hollywood, he meanwhile worked on a chicken farm and wrote the sounds for some celluloid blockbusters as an anonymous “music slave” for the major studios.

As a convinced communist, Paul Dessau settled over to the GDR in 1948. He worked with Bertolt Brecht as well as his fourth wife, the stage directing idol Ruth Berghaus, and had a significant influence on the socialist music scene and stage art. He became a music teacher for children at his son Maxim’s school in Zeuthen. His works were taught in schools, his “Thälmann-Kolonne” became soon very popular, but at the same time he was condemned as a formalist because of his often idiosyncratic tonal language. He became a GDR state composer who was mainly celebrated on the outside, but sharply criticized on the inside.

The film portrait consciously traces the contradictions in Dessau’s character, life and work and embeds the man and his music in the historical context. The cinematic approach to the protagonist and his sound cosmos becomes a jigsaw puzzle, both literally and figuratively, whose individual – often disparate – pieces slowly come together to form an overall picture.

In staged concert scenes, artists translate his sound into body language and tongue-in-cheek cartoons his song humoresques into associative picture stories. Musicians play in quarries, orchestral works become music clips, pupils of the “Paul Dessau” comprehensive school in Zeuthen walk in the footsteps of their namesake. Historical recordings evoke the world and stations of Dessau’s life, and the composer himself has his say in rarely shown archive scenes. In addition, interview partners – from politician Gregor Gysi to former concert hall director Frank Schneider or the American jazz composer Jack Cooper as well as composer and pianist Steffen Schleiermacher – try to create a portrait of Paul Dessau not only with words, but actually by doing a puzzle.

Music takes on a life of its own in the moment of writing, believes Jörg Widmann. It assumes its own form, becoming a living being that forges its own path. As such, it remains a fragment, because it is not what he, the writer, had intended.

For Widmann, the image that best describes this progression is a maze. Today, this has become the theme that runs through his life’s work, one that he has explored musically over the course of six distinct pieces. In the maze, one gets lost and bumps into things. There are moments “where it doesn’t go any further. And that is something that I often experience as problematic and very painful in composing. As happy as composing is.” Increasingly, he is led out of the maze of composing into which he has been drawn by his other role of clarinettist (for many years considered one of the world’s best) by his activities as a conductor.

We follow Jörg Widmann into his maze, reaching for the thread that runs through his life and work. Together with him, we experience the ups and downs, the euphoric moments as well as the moments of crisis that are brought about by the process of writing. We encounter him backstage and on stage. And we discover that it is in fact a bundle of threads that intertwine to form a tangle, whereby the composer without the clarinettist, the conductor without the composer, or Jörg Widmann without the human, is inconceivable.

The film accompanies Jörg Widmann in the composition of his trumpet concerto “Towards Paradise (Labyrinth VI)”, commissioned by the Leipzig Gewandhaus Orchestra and the Boston Symphony Orchestra. We witness the piece take shape, from the first drafts to the premiere performance. As clarinettist and conductor, we see him at the Salzburg Festival, in the Boulez Hall and at the Konzerthaus Berlin, and experience this ‘universal musician’ alongside Daniel Barenboim (as pianist), with the celebrated violinist Anne Sophie Mutter, for whom he composed his String Quartet No. 6, and during a concert tour of Taiwan together with his sister, the violinist Carolin Widmann.

We follow the AI as it reconstructs Beethoven’s 10th symphony and watch it perform with Robbie Williams, and we see how pianist Dirk Maassen at the Sony Science Lab in Paris and saxophonist Asya Fateyeva at the Hochschule für Musik Nürnberg interact with AI in real time, and how Spanish professor Eduardo Miranda in Plymouth is using quantum computers to create music entirely from scratch.
