Active performer of the new music stage, Léo Belthoise is pursuing an international outreach of his projects as a soloist, chamber musician and experimental artist. Initially supported by the Swiss Foundation for Young Musicians, laureate of the Fonds Régional pour les Talents Emergents d’Ile-de-France in 2021 and associate artist of the RHI Think Institute, he is a permanent member of Ensemble Sillages and Barcelona Modern.

He has performed as a soloist and chamber musician in prestigious venues such as Porto Casa da Musica, CCB in Lisbon, l’Auditori in Barcelona, Radio Concert Hall in Geneva, Tonhalle in Zürich, Cortot Hall in Paris, the Arsenal in Metz, the ZeitRaüme Biennale in Basel and the Reiter Theater in Munich, including radio-broadcast on France Musique, Antena 2 and Bayerischer Rundfunk. With the Trio Pangea, he is currently recording a four volumes anthology for the Naxos company.

Born in Montmorency in 1991, he studied violin, chamber music, harmony and analysis in France, then with Raphaël Oleg at the Musik Akademie Basel. His first solo album dedicated to the works by Manon Lepauvre and Toshio Hosokawa was released in 2023 and received critical acclaim. The press describes his playing as “particularly intense, underlined by total emotional commitment”.

He now develops various immersive forms of artistic expression with his production company Liquid Season, with the support of the Institut Français.
