Ligue Santé Mentale has announced an open call to the public to join Luxembourgish singer Serge Tonnar in a participatory choir for the filming of the music video for the song “Alles Ass Ok” in Luxembourg-Kirchberg on Sunday 11 October 2026, as part of Mental Health Weeks.

The event will begin at 14:00 and is open to everyone, with no previous singing experience required. The exact location in Luxembourg-Kirchberg will be communicated to registered participants.

For several months, an initial group of participants has been taking part in the project alongside professionals and artists. The filming on 11 October will mark a new stage in the project, with the choir opening up to a wider public.

According to Ligue Santé Mentale, “Alles Ass Ok” forms part of an artistic and participatory initiative centred around mental health and is not limited to the production of a music video. The project also aims to highlight the people taking part, their experiences and the journey they have made together.

Through music, singing and collective creation, the project aims to contribute to opening up dialogue around mental health, combating prejudice and highlighting the importance of connection, participation and inclusion.

Ligue Santé Mentale has invited anyone interested in taking part to join the choir, with no musical prerequisites or previous singing experience required. Interested participants can register via the dedicated registration link. Practical information and final timings will be communicated following registration.

The project is led by Ligue Santé Mentale and Fondation EME, with the support of Œuvre Nationale de Secours Grande-Duchesse Charlotte, in collaboration with Two Steps Twice, and forms part of Mental Health Weeks.
