Marie Brassard is an actress, writer, and director. In 2001, she began a solo career and founded her own production company, Infrarouge.

Since then, in close collaboration with musicians and visual artists, she has created surrealist theatre with virtuoso acting and innovative video, light, and sound. Blending voices and music across different levels of reality, her productions take us into a world where the lines between private and public become blurred, and the relationships between humans and technology become intimate.

Expressing a singular voice in the theatrical landscape, her works have been presented and warmly received in many countries in the Americas, Europe, Japan and Australia. 

Quaternaire represents Marie Brassard and Infrarouge in Europe (apart from Germany and the Netherlands) and in Australia and New Zealand.
