Audiovisual EEG performances
EEG-based musical performances have been around since the 1960s, starting with pioneers such as Alvin Lucier and David Roosenboom. It requires a highly trained EEG performer who is able to intentionally maintain a state between excitation and inhibition of control, modulating the sounds generated by the synthesizer. Together with a synthesizer artist adapt in responding to the signals created by the brain, a unique and highly improvised sonic performance can be created, revolving around physical stillness, inner concentration, trance and mental freedom.
Both the EEG-performer and the musician are seated on a stage, in front of the audience. Loudspeakers are placed at the sides of the performers. The EEG-performer has a sound monitor to improve the quality of neuro-feedback during the performance. Sometimes visual aids are used. The EEG, it’s power spectrum and resultant control signals are projected behind the performers, allowing the audience to identify the relationship between the brain signals and the movements of the sonic composition.
