The North Sea Jazz Festival is the largest indoor music festival in the world, known globally as the event where the past, present and future of jazz are featured within three days. Next to a firm base of jazz as the festival's staple music genre, many others, such as blues, soul, funk, or hip hop, pass by. In 1980, legendary American singer-pianist Ray Charles gave an unforgettable performance at the North Sea Jazz Festival in The Hague. This mercurial artist pioneered soul music in the 1950s, and helped integrate country, rhythm and blues, and pop.
