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, American soul legend Ray Charles brought the Raelettes and the Ray Charles Orchestra to the North Sea Jazz Festival in The Hague. With the full force of these two groups behind him, Charles showed why throughout his storied career he has been viewed as one of the most recognizable voices in music.
