The Prinsengrachtconcert is an annual open-air classical music concert held annually in August since 1981.
The orchestra is situated on a pontoon anchored in front of the Hotel Pulitzer.
Many of the audience watches and listens from boats.
Traditionally the concert is closed with a rendition of one of the city's anthems, "Aan de Amsterdamse grachten".
The first Prinsengrachtconcert on ice was held in February 2012.
