Also known as "Schnäuzel"; we have also virtually taken over. We learned a lot about the history of Chemnitz from him, as he was the head sound engineer at the Stadthalle Karl-Marx-Stadt from 1974 to 1980. He is a trained theater sound engineer and has a degree as a master craftsman for radio and television technology. Even without Callas on stage, he conjures up a clear-as-a-bell sound for us.
