Dear Sophie -
The seminal work of the theater director ROBERT WILSON is Einstein On The Beach, a modernist operatic 5 hour epic featuring a score by PHILLIP GLASS his collaborator and the choreography/performance by LUCINDA CHILDS. The set design is boldly architectural, minimal and dramatic, Glass's score hypnotic and Child's movements repetitive and exacting.
I attended the U.S. premier at the Metropolitan Opera House in New York in 1976 and again when re-staged in 1984. It had lost none of its passion and verve.
