Mysteryland is a series of electronic dance music festivals held by the Netherlands based promoter ID&T.
Established in 1993, Mysteryland is the longest running dance music festival in the World and the connection to Woodstock underlines the importance of the modern festival in youth culture.
In 2011, an international edition of Mysteryland was held in Chile, the first to be held outside the Netherlands.
Over the Memorial Day weekend in May 2014, the first U.S. edition of Mysteryland was held at the Bethel Woods Center for the Arts, the site of the notable Woodstock festival held in 1969. Headliners included Kaskade, Moby, Steve Aoki, Dillon Francis, and Flosstradamus. It was after the inaugural mysteryland USA that the bird which is part of the festivals logo was coined the name Ralphie.
