Chances are you have never heard of Robert Wilson, unless, of course, you followed the Avant-Garde scene of the 60s, 70s and 80s in New York and Europe. Then you'd know that Wilson is probably the most influential figure of the Experimental Theatre Movement, a creative genius and progressive thinker that brought stage performances into the new era of performance art. As a highly prolific collaborator with some of America's most notorious underground icons like Philip Glass, Tom Waits, David Byrne or William S. Burroughs (all of whom appear in the documentary) Wilson managed to awe the theatre world abroad with spectacles that lasted sometimes as long as a full week.
