Every year, the Berliner Philharmoniker hold a kind of classical-music fête with a bright, cheerful concert to end the season. In 2009 about 22,000 people had come together at the Berlin Waldbühne to enjoy the traditional summer picnic concert. The theme of the evening was “Russian rhythms”, and star conductor Sir Simon Rattle, the Berliner Philharmoniker and Yefim Bronfman, one of the most famous pianists in the world today, presented a superb selection of Russian music.
