‘Ground’ is an audiovisual performance in which graphite drawings are used as a control interface for several electronic instruments. Drawing, erasing and touching become the main gestures for a unique audiovisual composition. Graphite is a conductor for electricity. By using graphite as a variable resistor (instead of a standard knob) the pitch, amplitude and sound color of sound generators can be controlled. Ground is developed in collaboration with Jeroen Uyttendaele.
