But it's okay, there's worse. Squeaky colours, rounded corners and disco balls - the Hörsaal is full of them. The retro style corresponds to the music programme, especially on weekends, when DJ Hacki starts up his "Beatbrauerei" or when the WhatDaFunk? sound system invites you to a "Funkotronic" evening. Live concerts also take place here from time to time. Marina & The Diamonds, Duncan Townsend and Frida have already played gold in the auditorium. Applications from newcomer acts are also welcome at any time.
