A Musical Brainwave Performance at the DECONism Gallery in 2003. "REGEN3 will present the latest developments in EEG brainwave music research, by presenting an ensemble comprised of Toronto jazz musicians playing music which is driven and altered by the brainwaves of the audience. Audience members can become part of an advanced mass EEG system which uses audience brainwaves to control the music and lighting environment: a truly 'smart' building. Join us and see what happens when the mood of the environment is "regenerated" by the collective consciousness of the attendees."
