In this self-organizing operatic form—with spoken text, not sung—Thomas Jefferson falls asleep while writing one of his famous political documents and receives a lecture from Hypatia of Alexandria across continents and over centuries of time. Auditory evoked responses, event related potentials (ERPs), detected in the electroencephalograms (EEGs) of two biofeedback performers are used to guide the emergence of an electronic music score, to arrange chunks of spoken text, and to edit video images with symbolic associations, all in real-time. Two improvising musicians respond to each brainwave performer, and a narrator provides threads of continuity drawn from a variety of historical texts related to the subjects at hand.
