Music for Sax and Boxes is a 15 minutes piece for tenor saxophone, electronics, and four specially designed boxes. The boxes are made of the same material, but of different sizes. Attached to them are contact speakers that emit the sounds of the live saxophone (as well as other pre-recorded and composed sounds). As the sound vibrates through the surfaces of the boxes, it is transformed by the physical properties of their material, size, shape and the volume of their internal space.
