On 10 December, the Festspielhaus will be transformed into a gigantic sounding body - with music down to the last vein. Dance and sound everywhere: not only in the hall, but also in the foyer and on the corridors and stairs. For the "Sounding Festspielhaus", the doors open to friends, neighbours and all visitors who simply want to drop by. 25 years of the Festspielhaus: be there when the whole house comes alive for you!
