Johan Vandermaelen (°Brussels 1962) is a composer, improvisor, maker of instruments and installations. Meeting Hugh Davies in the late 70's triggered the interest for making electro-acoustic instruments. In the early 80's he attended the Royal Conservatory of Antwerp where he studied electronic music under Joris De Laet. As an improvisor you could find him in several groups and combinations. 

He composed music / sound design for films (several for Magnum Photo Agency) and played music by and worked with Alvin Lucier, George Crumb, Phill Niblock, Tom Johnson a.o. He teaches 'electronic instruments' at KASK & Conservatorium. He is part of Atelier Tim Duerinck (HOGENT Futures through Design) where he develops a microphone for cello.
