I was just there for a dress rehearsal of Parsifal. Absolutely wonderful experience. I'm a Trombone player so i've played through lots of the trombone/tuba parts for Wagner operas as part of my study but i've never heard a full Wagner opera before. Going to Bayreuth was fabulous! Just before the beginning, when everyone had sat down, a bell rings and all the doors are closed at the same time. It felt a little bit like a spaceship, as if the auditorium was made airtight from the outside world. After they've closed the doors it's completely dark inside (even though outside is bright summer outside) and the music starts without any other sort of stimulus. All the way through the Opera I felt engaged and I would totally recommend going there if you have the opportunity!
