The participatory youth opera "Der Letzte Tag" (The Final Day) tells the story of a future dystopian society in the year 2084 that has ignored all warnings, outrages, and protests from the past (2021) by the young generation and continued to take its course without consciously facing the crises, driving blindly and lazily towards its doom and downfall. In this future setting, the only society members that are left are narcissistic, nihilistic, selfish, or naive 'all be good'-people. Now, it's the 11th of June 2084, they come together for the last time to celebrate the final day, the end of the world! Because: It is what it is! What shall we do instead? There are no alternatives anyway, so let's have a glass of wine at least! The play starts with a so-called "Outrage-choir" that plays in the past (2021), showing people's awareness of urgent world problems. But these have been ignored and the feeling of powerlessness took over. Then the play jumps into the future and several party scenes – that are the connecting dot of the side-narratives – show the build-up and dramaturgy of the 'final day'-party: cringe atmosphere as people are coming too early, escapism, then escalation. Between the party scenes that display the characters who represent the future society, the play shows dystopian flashbacks that provide the possible reasons for why the society ended up facing its final day: Racism, discrimination, fake news, as well as a new value system driven by perfection, efficiency, and superficiality. Aesthetically and musically each dystopian imagery for one of the possible reasons is presented in a different style e.g. an electronic loop subway-scene exploring racism, an operatic sleeplessness and self-doubt-aria, a house and trap social matching fashion show, and a narcissistic jazzy trio featuring narcissism in different contexts: at the workplace, in toxic relationships, in politics. Everything culminates in a final brindisi at the party where the society finally falls apart. Because shockingly, even in the light of the final seconds the society still doesn't properly listen to each other, breaks up in anger, or continues pretending to be happy and look perfect until the final moment. In the moment of the apocalypse, the play stops and "holds its breath". Instead of showing if the world really collapsed and instead of providing possible solutions to the problems that have been touched on, the ensemble rather raises a question: What if this would not be the final day? What if this would only be the last day of 'something old'? If tomorrow would be a new day, what would you like to do? With whom you would like to sit at a table? Or would it even be okay to simply be the same person that you are today? In the end, there is still a glimpse of ‘abstract hope‘. How hope is defined can be decided by each audience member itself. While the libretto and music have been written and composed by the ensemble itself, some musical and content impulses such as madness, manipulation, power abuse, do also arrive from Verdi's Macbeth, which has been watched and discussed by the ensemble during the project.
