Choros came into being in the winter of 2013 at the initiative of five musicians whose paths had already crossed before. Since it was founded, the ensemble has performed in various environments for diverse audiences, from Montreal to Petite-Vallée, through Quebec City and in a sound installation in Val-David. Over the years, they have undertaken several fruitful collaborations with well-established ensembles (Pentaèdre, ECM+, Quatuor Bozzini) and producers (Société de concerts de Montréal, Codes d’Accès, Maisons de la culture, Ahuntsic en Fugue, Pro Musica) and have given several premieres (works by Alexandre David, Matthieu Dumont, Carmen Braden, Alain Lalonde, Julien Bilodeau). Choros has also taken part in a Canada-wide project to showcase repertoire for wind quintet, is a recipient of a New Chapter Grant awarded by the Canada Council for the Arts and is a founding member of the Wind Quintet International collective.

Through its concerts and encounters with its audiences, Choros contributes to the vitality of chamber music while democratizing the classical repertoire and contemporary works, performing outside of the conventional concert hall (Botanical Gardens, Place d’Armes, Sala Rossa) in addition to performing for a versed public (Chapelle historique du Bon Pasteur, Salle Claude-Léveillée, Jeunesses Musicales Canada). Choros also engages young people in educational activities, in high school and music camp settings.
