Watch a specially prepared film by Australian/American avant-garde composer and musician, Warren Burt, in which he describes his reconstruction of one of Grainger's experimental machines, the Electric Eye Tone Tool. Lydia Kavina then presents a selection of original works for the haunting sound of the theremin, of which she is a leading exponent. She will also include a realisation for theremin of Grainger's 'Free Music' and answers questions from the audience.
