Juliette Adam on clarinet, Judith Hamann on cello and Léo Dupleix on harpsichord are Les Certitudes. Their music focuses on tones and tuning, working through long musical forms made up of layers and slowly displacing matters. Their music is composed by Léo Dupleix, while the musical direction is the result of a collective spirit. The ensemble came to life in 2021 as a means for developing acoustic music focusing on justly tuned tones and harmonies, taking as a starting point the physicality of instruments – resonating wood and metal. Their debut album Construire Sur Les Ruines D’un Passé Encore Fumant on Discreet Editions beautifully proves their musical point, it being a collection of strangely and differently harmonic pieces that are focused on a gently distorted sense of repetition and musicality.
