This page is dedicated to all the Stones, air, axioms project's live performances. Each of them is based on the characteristics of the venue, its architecture and historical significance.

Nowadays, information is circulating through cables and codes, however, before the advent of technology, the very acoustics of amphitheatres and religious buildings fulfilled this trans-mission function. The cathedral is one example. Partly con-ceived to enhance voice and music, it offers a wide resonance to support the religious discourse. These unique acoustics are part of its characteristics. This massive air volume is being enclosed and defined by stone. It acts as an amplifier of noise and forces listening and attention. The behaviour of the visitor/audience going through the building is thus being altered. The architecture constraining this air volume is complex and ruled by doctrine. The shape it is drawing constitutes both a symbol and an element of hierarchy for the listening situation within the space.

Creative process :

The site is measured metrically.
Its measurements are converted into the frequencies of its stationary waves.
A sound system is set up.
These frequencies are played using an organ and electronic devices.
The air volume in the space, set into vibration, is recorded.
Its shape and surroundings are recorded.
All the previous steps gradually constitute the performing modes that will shape the concert.
