We have a lot of things in Amsterdam, but not an open air theater which is big enough to hold the whole Royal Concertgebouw Orchestra. So what do these Amsterdammers do? They build a concert hall on a pontoon in the middle of Prinsengracht!
A few days ahead of the concerto the canal is already blocked by small boats, and when you live close to the venue you have “friends” who visit you once a year, only on this date.
One of the traditions of this concert is the last song of the program “Aan de Amsterdamse grachten”, sung in Dutch, by the [mostly foreign] soloist.
You can see the whole TV performance here. If you have problems viewing it abroad go to Instellingen and check the square behind Buitenland.
