This seminal work of avant-garde opera from composer Philip Glass and director Robert Wilson arrives full-circle, coming to France, the site of its 1976 Avignon Festival world premiere, at the tail end of this 2014 revival tour for a landmark Theâtre du Châtelet production and a first ever filming by award-winning arts filmmaker Don Kent.  Eschewing conventional narrative, the opera revolves loosely around pacifist Einstein’s relationship to the creation of the atomic bomb.
