Derivative Res is a performance which connects two standalone systems into an oscillatory dependency. The video of performance consist of a system of particles which lives upon a fragile equilibrium between control and chaos as subjected to oscillatory inputs. The physical system, under a constant flux of those inputs, behaves in random and unexpected manners, way out of the direct control of the performer, like a structure resonating in an echo of oscillations. The sound, mutating its form from ambient-based to more noise scapes, is the polyform trigger under which the system reacts, but it is also influenced by it, in a bidirectional exchange of inputs. A deep interconnection runs between the two components, thus to create a bonding synesthesia experience.
