[a]Void (2011, Hartmann & Graetz)
[a]Void was composed for Beethoven Fest Bonn 2011 by Hartmann & Graetz. Using fugitive material like dry ice and different chemicals, sounds are created with metal objects and water and processed in realtime with software patches and time based audio effects. This way Hartmann & Graetz create an sonic scape “out of nothing” filling the former void of no sound at all. In some parts of the performance they also use feedbacks and cirquit bending for creating musical elements.
