Polytechnique is a work dedicated to the 14 victims of the Polytechnique massacre that took place on December 6, 1989 in Montreal. It is the story of a man standing in the middle of an immense space covered with an oppressive dark and dense fog. Standing alone in the middle of his opaque and confused psyche, reduced to a fear that only leads to hatred. It is also the story of fourteen young women standing against a white wall. Standing and terrified, in the middle of a nightmarish storm. Standing and terrified. Then stretched out and unconscious in front of a red wall. Pierced, forever motionless and light ... This is the story of fourteen young souls floating calmly between heaven and earth on the immutable ocean of the Incomprehensible. It is at the heart of the troubling abysses of humanity of this ocean that Polytechnique, the second large-scale opus of the young composer Jonathan Dagenais, plunges us.
