In honour of the centenary of the birth of perhaps the greatest violinist ever to grace the stage of Carnegie Hall, Isaac Stern, one of our greatest violinists today, the imperious Maxim Vengerov, played a concert of some merit with his piano playing partner, the Russian wunderkind Polina Osetinskaya. The programme had no hint of Russian music, not even in the four encores and perhaps that is why the evening didn’t really take off until the very end.
