North Sea Jazz Festival
One of the biggest indoor jazz festivals in the world. The first edition of the North Sea Jazz Festival took place in 1976 with six venues, three hundred artists and about nine thousand visitors. In 2006, the festival moved to its current, bigger, location in Rotterdam. This year, the organisation expects more than a thousand musicians, spread out over 150 performances and thirteen different stages. Though the numbers of visitors were between 65.000 and 70.000 in recent years, the festival still manages to retain its intimate character.
