In the hallowed acoustics of the 12th-century Chapelle Saint-Martin in Bignac, France, a remarkable sonic exploration unfolds through "Radiesthésie", the collaborative album by French improvisers Bertrand Gauguet and Jean-Luc Petit. Released on March 21st, 2025, under the UNRec label, this collection of five improvisations serves as a testament to the duo's profound synergy and inventive artistry.

Gauguet, wielding alto and baritone saxophones, and Petit, navigating the depths of the contrabass clarinet and the heights of the sopranino saxophone, engage in a dialogue that transcends conventional musical boundaries. Each track presents a unique interplay of timbres and moods, reflecting the spontaneous nature of their improvisations. The chapel's resonant space becomes an integral participant, its stone walls amplifying and enriching the organic textures produced by the instruments.

The album's titles, such as "Le pendule de Thöt" and "L'antenne de Lecher", evoke a sense of mysticism and exploration, perhaps alluding to the ancient art of dowsing - 'radiesthésie' in French. This thematic choice mirrors the musicians' quest to unearth hidden sonic landscapes, much like dowsers seeking unseen sources beneath the earth's surface.

Both artists are integral members of Le UN, an improvisation ensemble characterized by its non-hierarchical structure and collective artistic vision. Gauguet, based in Paris, has an extensive background in both solo and collaborative contexts, delving into the realms of new music and electronic compositions. His work often emphasizes the exploration of frequencies and the meditative qualities of sound. Petit, with his focus on sculpting sound material through improvisation, has collaborated with various ensembles and artists, continually pushing the boundaries of acoustic research.
