Chion's "Requiem" was realised in the studios of the Groupe de recherches musicales (GRM) in Paris (France) and premiered on March 19, 1973 at the Théâtre Récamier in Paris.

To celebrate the 50th anniversary of the first performance, Northern Lights Project is embarking on an ambitious project to perform this work live in a number of locations in Ireland in 2023, starting with Derry's Guildhall exactly 50 years after the first performance.

“Chion's Requiem probably represents one of the defining moments of the musique concrète canon, a work all other pieces must be judged by and one of the few absolute masterpieces of the genre.” – Modern Illusions
