Sound, image and speech become elements of a composite work, that move for a code able to neutralize the power devices from an analysis on the present. A code reprocessing itself through aesthetics and politics, turning sounds and images into active catalysts of factual vectors. New global auditory avant-gardes use musical matter to express concepts crossing contemporary time, bringing out inner contradictions that feed their own creativity. The artistic production is before anything else an investigation and communication infrastructures become the privileged place for its enactment.
