Daily tous les jours are the creators of I heard there was a secret chord, a sound-based installation on display at the Herron School of Art and Design Galleries. Created in 2017, secret chord was a commission from the Montreal Museum of Contemporary Art in collaboration with the National Film Board of Canada. The installation was created for the Leonard Cohen: A Crack in Everything exhibition during Montreal’s 375th anniversary celebrations, one year after the musician’s passing.
