Einstein on the Beach revived for London 2012 Festival

Composer Philip Glass and director Robert Wilson have revived their iconic opera Einstein on the Beach, which is being performed in Britain for the first time as part of the London 2012 Festival.

It is one of the most radical and avant-garde operas ever staged and at 5 hours with no interval, it is considered a challenge to most of its audiences.
