From May 29 to June 13, the "Blaues Rauschen" festival invites you to experience digital sound experiments and electronic music in so-called "sound spaces" with concerts, performances and installations. The Essen-based association open systems e.V. opens up spaces for discourse on the relationships between man and machine, analog and digital with workshops and lectures. The events take place at Westphalian venues in Bochum, Dortmund, Gelsenkirchen, Herne and Witten, among others.
