Chœurs is a joint musical album by Bertrand Cantat, Pascal Humbert, Bernard Falaise and Alexander MacSween released on Actes Sud label on 16 December 2011, although it was made available for downloads on 21 November 2011.

But Cantat did sing actually in productions in Bordeaux region on 28 June 2011 at the Rocher de Palmer in Cenon[2] followed by shows in Bourges, Reims, Brest, Lyon, Geneva and Athens.

His scheduled appearance in Montreal's Théâtre du Nouveau Monde in May 2012 was cancelled after pressure from feminist groups and his role was taken over by Igor Quezada.

The album was released as a book disc of 32 pages and an introduction to the play by Moawad and a picture gallery in black and white and in color by Jean-Louis Fernandez.

Moawad also added two Quebec artists, the guitarist Bernard Falaise and drummer Alexander MacSween to complete the rock quartet.
