In today's International Herald Tribune a portrait of the Russian poet Yevgeny Yevtushenko, who wrote the poem Babi Yar, which formed the basis of the 13th symphony of Dmitri Shostakovich. For more than a decade Mr Yevtushenko has been living with his family in Tulsa, Oklahoma, where he teaches at the university. ( PS: I am aware that the web pages about the poem and the symphony contain annoying mistakes. E.g., Babi Yar is near Kiev in the Ukraine, not Russia, and Katchaturian was Armenian, not Georgian, even though he was born in Tblisi. Still, in the little time that I had available I could not find any better comprehensive online information about these works of art. )
