Every Summer, close to the full moon, a group of sound artists walk up montain carryng radios. Modulation is a micro radio camp run by artists Emma Loriaut and Julien Clauss for the past 16 years. Participants have to have a battery-operated or acoustic sound set up, a tent, some food and a portable FM radio. Over the 24 hours, participants chose their time slot, focusing on environmental sounds, day light or moon presence, temperature and the mountain itself. In this way the landscape dictates the line up. This concatenation sound piece came out of the 26 radio concerts that took place between 4 - 5 July 2026, at 1700m alttitude in the Devoluy Mountains. Every time you hear a cut, a new musician is playing.
