Music Festival Oslo, the former Music Day, has its background from the French festival Fête de la Musique, held annually on 21 June. The world's most comprehensive international music festival was conceived under Jack Lange in 1982, then Minister of Culture in France. The event came to Norway through initiative from Oslo municipality after meeting with Lange in 1992. In 2006, we were able to celebrate our 15th anniversary. Fête de la Musique, the National Music Day, or the Music Festival is now fined in more than 100 countries worldwide. Common rivals are that the music is mostly outdoor and that everything is free to the public. The artists act free of charge. To be formally approved as an international organizer of Fete de la Musique, it is assumed that the festival is 21 June. This has proved difficult in Norway, partly because of our holiday development, and it has been necessary to add the event to a weekend. In recent years, we have chosen to get stuck on the first Saturday in June. In spite of the fact that Music Festival Oslo is inspired by Fete de la Musique, we are formally not part of this movement.
