Vladimir Jurowski just finished a four-city North American tour with the London Philharmonic Orchestra, where he's been the chief conductor since 2007. Last month, the Philharmonic renewed his contract through 2018, and critics have frequently praised his artistic bond with the ensemble. But along with his London ties, Jurowski also has some strong feelings about his native Russia, whether it's parsing the political subtexts in Soviet repertoire or speaking out on present-day civil liberties.
