This is a compilation of four short video films, made in the La Tourette Dominican monastery near Lyon, which was constructed in the early sixties according to the plans of Le Corbusier and with the participation of mathematician, musician, and composer Iannis Xenakis.

A static camera presents a narrow angle of observation, a detail of space between the glass wall and a pillar. Here the camera records the happening from the inside. It presents a surface of concrete block elements and a fissure, through which we occasionally see the simultaneous movement of wooden sticks. The picture does not show the source of the sound, nor the type of instrument used by the invisible musician. (VD)
