Improvisation/∆Spaces is an comprovisational performance piece in three movements for laptop quartet and fixed media, composed by the CPU Quartet.

From our very first rehearsal we began with the idea of using the fixed media to simulate an acoustic space which we could inhabit as instruments. Discussion was had of experimenting with creating a network of signal paths between our laptops and the venue computer, possibly running convolution reverb in order to spatialize our point source instrumental sounds throughout the performance space. We considered taking primitive impulse responses of particularly reverberant spaces around Montreal to facilitate this. A simple narrative form was suggested where a spatio-morphological shift would take place transporting the performance from this indoor reverberant space to an open outdoor space. Read on
