André Castro (b.1983) is a sound artist from Lisbon, Portugal, graduated in Sonic Arts by the Middlesex University. He develops works which, although often different in form, have in common the employment and exploration of sound and technology. A great part of these projects has been created in collaboration with designers, visual artists and choreographers. In recent years he has developed an interest for the potential and imaginary of the radio. For this medium, he has created the sound installation Radio Fragments, and the radiophonic documentaries Subterrâneos de Lisboa, and Boat People. Since last year he has begun to explore the world of electronics. Such incursions have resulted in the Tactile Noise project.
