We show the extraordinary film project by the renowned cellist Tanja Tetzlaff. For the film, she visited places with her cello that visibly bear the effects of climate change. Among others, she played the Bach Suites 4 & 5 live in the Harz Mountains, on the French Atlantic coast and the Aletsch glaciers. Tanja Tetzlaff was honoured with the OPUS Klassik 2023 in the category "Innovation Award for Sustainability".
