"Stones, Air, Axioms" is an ongoing art and research project by French soundartists Jean-Luc Guionnet and Thomas Tilly, dealing with the complexrelationships between sound and architecture. Delme is the third phase withinthis venture. By virtue of its history and exceptional acoustics, Delme's formersynagogue is the ideal setting for a customised, on-site sound installation. Bysupplementing the built space with frequencies, as well as voices, instrumentalnotes, rhythms and silence, the artists offer everyone a special listeningsituation: whether this listening is drifting or attentive, static or mobile, itis guaranteed to give visitors a different perception of the place, which isremoulded by the volume of air it contains and by the sound travelling throughit.
