Michael Haas, author of the book Forbidden Music - about the generation of Jewish composers murdered, obliterated or exiled by the Nazis - was curator at the Jewish Museum in Vienna of a fabulous exhibition about Julius and Erich Wolfgang Korngold several years ago. He has now posted on forbiddenmusic.org a very substantial essay entitled The False Myths and True Genius of Erich Wolfgang Korngold, lavishly illustrated with both visual and aural material.
It is wonderfully written and the story emerges powerfully with all its complex, baffling and ultimately tragic elements in sharp relief. Did Korngold die too young because of the stress caused by his own sense of "irrelevance"?
Do give it a read. And a listen.
