The Opera is a funny story, during our night tour we happened upon the stage crew setting up an outdoor stage and as interested citizens asked what it was for. The answer: "Oper für alle" which we discovered was not actually opera but the Bayerisches Staatorchesters.
The program included:
Debussy: Prélude à l'après-midi d'un faune (ATTACCA - Jugendorchester des Bayerischen Staatsorchesters)
Debussy: La mer
Strauss: Eine Alphensinfonie op. 64
Conductor: Kent Nagano
The first piece was performed by the Youth Orchestra, an initiative to train up the next generation of orchestra members. I found it very amusing and had to take a picture of the actual orchestra hanging out, waiting to play the next piece, in tails on the Opera steps. There was an encore by the main orchestra but I can't remember the name. I have learnt one very important lesson though, an open-air concert is wonderful but sitting for 2 hours on a cobbled stone floor is very uncomfortable.
