Crown Princess Mette-Marit and Crown Prince Haakon at 2012 Nobel Peace Prize Concert

Crown Princess Mette-Marit, Crown Prince Haakon and Marius Borg Høiby attended the Nobel Peace Prize Concert in Oslo. The Nobel Peace Prize Concert (Norwegian and Swedish: Nobels fredspriskonsert) has been held annually since 1994 on 11 December, to honour the Nobel Peace Prize laureate.

The award ceremony on 10 December takes place in Oslo City Hall, while the concert has been held at Oslo Spektrum, with the attendance of the laureate and other prominent guests. The Concert is broadcast to a global audience and reaches up to 350 million households in 100 countries.

The concert features performers from a wide range of musical genres, the exception being the year of 1995, when a classical concert was held instead. Several editions of the concert are recorded, with different lengths and content, for airing in several countries. The hosts give descriptions of the winner's work, an interview with the winner is shown, and the winner gives a speech during the concert.

Since planning starts in January, the artists invited to the concert aren't typically connected to the winner, who is announced in October. However, a few late additions are usually made to reflect the winner. Originally, the show was hosted by Norwegian celebrities or television personalities. However, since the year 2000 hosts have with few exceptions come from the United States of America. The Norwegian Radio Orchestra is the main orchestra every year.
