POWEr is a performance based on high-voltage electromagnetic
perturbations, by Alexandre Burton and Julien Roy. Using an
audio-modulated Tesla coil as a live instrument, electrical arcs are
generated and transformed in an ongoing, realtime audiovisual process.
Electricity is used as a subtle yet intense material, manifested as an
instrinsically synesthesic phenomenae.
