The groundbreaking opera "Einstein on the Beach," a collaborative effort between Robert Wilson (direction), Philip Glass (music), and Lucinda Childs (choreography), shattered conventional operatic norms and pushed the boundaries of artistic expression. This 4½-hour minimalist masterpiece, first staged in 1976, eschewed traditional narrative, opting for a series of abstract, visually striking sequences complemented by Glass's hypnotic music and Childs's innovative choreography.
