The Jewish Chamber Orchestra Munich, mezzo-soprano Shachar Levi, and conductor Daniel Grossmann present songs by Mieczysław Weinberg and orchestral works by two composers who have all but vanished from history. Jozef Koffler, a Polish Jew, was captured with his wife and young son by German troops in the city of Lwów in 1944, deported to the ghetto in Wieliczka and murdered by one of the German Einsatzgruppen near Krosno where he and his family had been hiding after the liquidation of the ghetto. Joel Engel was born in Ukraine and moved to Mandatory Palestine in 1924. Finding it difficult to adapt to life there, his health declined, and he died in 1927. He did much to keep the traditions of European Jewish music alive and moved in circles that included Heifetz, Godowsky and Piatigorsky.
