Can much can I rave about this place? The building itself is beautiful, but the main concert hall is something else. The acoustic is perfectly adjusted by panels on the ceiling that can be mechanically moved before the concert. It doesn't happen every time, but I saw it once before an open rehearsal and it was very cool. You can also get seats behind the orchestra, which gives you the same view of the maestro as the musicians, again a very different experience. On the Main building you can have dinner or coffee and there is a nice gift shop.
The only problem is that it is in a dangerous area of São Paulo, so if you are not used to the city, take a taxi and be safe.
P.S. the screen at the picture obviously didn't stay down during the concert.
