_ Eaux-Fortes _ + Cigvë à la Société Étrange

The duo Eaux-Fortes, formed in 2023 by Hervé Boghossian & Catherine Guesde, is a duo of electric guitars oriented toward the cosmos. The setup features 2 amplifiers lying on their sides, with speakers facing the sky. The guitars placed on them produce panoramic feedback, each with its own distinct, fairly raw sound, without effects. Throughout the performance, a ballet of guitars on/above/beside the amplifiers alters the sound waves and their textures through changes in distance and position; the slightest movement can change everything at any moment. Ripples, beats and interference are the essential elements of the resulting sound.

Catherine Guesde (guitar) is a philosopher, musician/composer and former rock critic (New Noise magazine). She develops an electric guitar practice that uses effects pedals to reveal the depth of frequencies, playing small, muted melodies that sometimes emerge from the continuous sound being produced. She performs in the guitar-and-effects duo M[[O]]ON (post-rock, drone), and solo guitar and effects under the name Cigvë (drone, folk, noise). In 2023, she toured Argentina with Romain Perrot/Vomir, Céleste Gatier and Argentine musician Leandro Barzabal. She has published two books: Sur la noise with Pauline Nadrigny, « The Most Beautiful Ugly Sound in the World » (Editions MF), and « Penser avec le Punk » (PUF/Vie des Idées), a collective work she coordinated. https://www.youtube.com/watch?v=Afi-9gGJM4Y https://mmli.bandcamp.com/album/lore

Hervé Boghossian (guitar) is a musician, composer and improviser who has been exploring sound as material for 25 years, taking a minimalist approach on experimental stages in Europe, the United States and Japan. He moved on to computer-based sound processing (Mouvements, Raster- Noton, 2004), then to feedback as a source (F.E.R For Eliane Radigue, Confront Rec., 2016) and the exploration of acoustic folk guitar, between the American Primitive tradition and sound-based music, particularly in recent years through a series of long compositions (for performance). He has collaborated with major figures including David Grubbs, Günter Müller, AMM, John Tilbury, Yann Gourdon... and developed projects such as Plateformes with Matthieu Saladin and Stéphane Rives, Harsh with François Rossi, and _ Eaux_Fortes _ with Catherine Guesde. His acoustic duo with Tetuzi Akiyama, formed in concert in 2006, eventually gave rise to the album Suketchi (Tour de Bras, 2019). In 2022, he launched the project L’Ensemble In(dé)fini, whose first collective composition, « Soufflements Cardinaux », with Owen Gardner (Horse Lords), Merve Salgar & Félix Chaillou-Delecourt, was released on vinyl in November 2025 on the Montagne Noire/GMEA label. In March 2026, he released the album « Arsta » (Rvbmusic - BC), the first recording by his new trio « Iota » with Kristofer Svensson & Ryan Packard, who will also join Anne-Françoise Jacques to form the line-up of Ensemble In(dé)fini #2, premiering in 2027. He also premiered his first piece composed for church organ, « Radiances Furtives », in concert in Berlin in September 2026. It echoes the album « Prémices 4/4 (for pipe organ) » (Rvbmusic-BC), released in May 2026 and based on improvisations on the instrument, some featuring Félix Chaillou-Delecourt. He currently performs solo in concert: acoustically, « Fragments de Futur » moves between composed fragments and sonic improvisations, creating a live process of composition in real time through deep listening. Electrically, « RVBruit » shifts the guitar’s processing through feedback, using the relationship with the amplifier lying on its side as its sonic foundation.
