I heard and saw a tour of the opera house and the Tosca von Puccini performance. Both were a great experience. I would also recommend taking one of these really detailed and interesting tours in the opera house before visiting an opera for the first time. The opera experience is much more intense when you know the background history of the Semper Opera. Starting from the first opera house, through its Brandt, the reconstruction, the materials used, the artists who participated, the representation and meaning of the paintings. The sound experience itself should be excellent from every seat.
Always my pleasure!
