Audio and visual performance, Tempest associates the analog instruments of Franck Vigroux with the visual algorithms of Antoine Schmitt, to create a real system-universes of pure chaos, that can be seen in the movements of millions of particles and can be heard through the roaring of air. By manipulating the internal forces of this chaos, the performers give birth to audio and visual shapes that develop in time, with more or less stability, more or less evidence. Tempest recreates the sound and fury of these original maelstroms within which it searches for the origin of form.
