The Aalto Theater in Essen, designed by Finish star architect Alvar Aalto. I went to see a lot of operas and ballets performed in the Aalto Theater. I was one talking about the "white head fraction". That's because the age average at one of the performances (especially Wagners Parsifal) is mostly above 60. As the German society is getting older and older I see dark clouds above the Aalto. I waited for that photo a long time.
