Every year there’s a festival of classical music centred on Amsterdam’s canals known as the Grachtenfestival. It starts today.
Lots of the events are free, including the highlight event, when boats cram the canal outside the Pulitzer Hotel, and the canals are lined with music lovers for the Prinsengrachtconcert. The concert is free – but be early to find a space! It’s also broadcast live on a couple of TV channels. The last song of the night is always “Aan de Amsterdamse Grachten” which means “on the Amsterdam canals” which cute since most of the audience is literally on the canal.
For other events check the official Grachtenfestival site – it is available in English and tickets are sold online.
There’s a promotional video out, conceptually it’s an Opera flash mob in the reception of the Amstel Hotel.
