Fellow classical music lover friend came to town. I pulled myself out of a few days of trying to sleep off a cold to go see a concert at Palais Garnier!
10 euro, hour-before-the-show tickets got front row second balcony seats.
(It took me a little while to decide that the curtain was not actually real.)
The hall itself was quite different from anywhere I've attended a concert before. The balconies are stacked and the arrangement is as if there are a bunch of small rooms surrounding the stage. Rather than rows of attached auditorium seats there were individual chairs of different heights in each room to provide the tiered viewing.
Although the hall is mainly used for ballet, the concert itself was a woodwind ensemble playing pieces by a french and a czech composer. It's always a different experience visiting a concert hall just to walk around the building and actually sitting down and enjoying what the space was made for.
On that note, if you're in Boston and haven't been inside the Christian Science Church, you should go. Better yet, watch an organ performance. They actually have one of the world's largest organs there and it is impressive to say the least.
