Silvia Rosani's music transfigures the past through the use of technology. A piece for chalumeau, the ancestor of the clarinet, preceeds a composition where household appliances transform into an electrical trio, which dialogue with the acoustic instruments in the tradition of cori spezzati. Audio feedback comes into play and colours the voice of the horn while, later, also making metal panels vibrate. DC and AC motors are handled like instruments and offers the opportunity to transuce electrical signals back into physical vibration, hence, deeply merging acoustic and electrical means of audio reproduction.
