Founded in 2010 under the impetus of Léo Warynski,the ensemble Les Métaboles brings together professional singers who are committed to the repertoire for a cappella choir. Their name, inspired by a composition by Henri Dutilleux (1916-2013), written around the idea of metamorphosis, evoking the choir's ability to transform itself according to the repertoire, while emphasising its anchorage in the contemporary epoch. The ensemble is dedicated to the full range of the choral repertoire and performs it for a diverse audience.
Although a large part of Les Métaboles' activity is devoted to the a cappella repertoire, collaborations with orchestras and instrumental ensembles are part of their musical season. The ensemble is therefore occasionally associated with the orchestra Les Siècles,l' Orchestre national d'Île-de-France, l'Orchestre de Normandie, l'Ensemble Intercontemporain and l'ensemble Multilatérale.
Les Métaboles is regularly invited to prestigious festivals and venues in France and Europe (Philharmonie de Paris, Opéra-Comique, Festival d'Automne, Musica in Strasbourg, Festival de Ribeauvillé, Musicales de Normandie in Rouen, Festival Voix Nouvelles in Royaumont, the Staatstheater Mainz in Germany, the Mozarteum in Salzburg).
Les Métaboles devotes a great deal of attention to contemporary composers by commissioning works, creating and performing the repertoire of living composers. The ensemble is also involved in the training of professionals with the ARCO composition academy and training courses for young choral conductors.
The Angels (NoMadMusic - 2021) is the ensemble's fourth recording after Jardin féérique (NoMadMusic - 2020), Une nuit américaine (NoMadMusic - 2016) and Mysterious Nativity (Brilliant Classic - 2014). Unanimously acclaimed by the critics, these recordings have established Les Métaboles as one of the best French choirs, both for its vocal excellence (precision, sound colour, homogeneity of timbre, etc.) and for the originality of the repertoires chosen.
The ensemble Les Métaboles was the winner of the Liliane Bettencourt Prize for choral singing 2018.
