Edwin van der Heide (1970) is working as autonomous artist in the field of sound, space and interaction. His original background is in electronic music. He graduated from the Institute for Sonology at the Royal Conservatory in The Hague in 1992. His current work is hard to define in the traditional terms of music, sound art or media art because he is permanently working on the edge and the characteristics of the used medium. In this sense the medium does not just mediate but is being explored, redefined, and finally composed with a musical approach involving a new communicating language. The fact that qualities of musical language are being used in development of the work does not mean that the presentation form of the work is related to the concert form known in music. The result can either be an installation, a performance or an environment.
