Event in which several artists can perform spontaneously and collectively. The Offene Bühne Zürich is a meeting point for improvising musicians and also performers for other art forms, which offers the chance to present joint improvisations on stage in ad hoc formations. A platform for music creation that basically has to do with improvisation and experimentation. But it is also a social art that enables everyone to perform on stage in a random or chosen constellation. The event is also open to the public. The Offene Bühne Zürich aims to promote diversity, freedom and respect among all participants involved.
