Today was my last day in Frankfurt.  I went to the symphony, and saw a moving performance of Bernstein's 3rd symphony.  https://www.alteoper.de/de/programm/veranstaltung.php?id=512510818  What was remarkable was that the program included a performance of the symphony with a Kaddish, performed by the author Samuel Pisar.  Pisar is a survivor of Auschwitz, whose parents and sister were killed by the Nazis.  He stood and recited a mighty prayer which was set with the music, and it was astonishing.  I just realized he's 89.  The Kaddish was a brutal indictment of violence and a rant against, and ultimately reconciliation with, God.  It was recited in English, but both the English and German were projected above the stage.  The German audience gave the performance an 5-10 minute ovation.  The performance was in the Alte Oper, which was destroyed during WWII but rebuilt in the 1960s.  Quite a wonderful evening.
