Kai's machine
A collaboration with architect Kai Franz gave birth to the idea of a sound trip inside one of his machines. The listener is enabled to hear the sand dropping on the horizontal carriage of the machine or the noise of the wheels on which it glides, as if the ear was actually leant against that surface. For the recording a contact microphone was used so that for a while one is immersed in a narrow space like a box until, towards the end, the sound emerges to the perception of a normal space.
