As the German violinist Clara-Jumi Kang began her round 3 performance of the all-important Tchaikovsky concerto, a small bird – possibly a sparrow – flew above the stage, circling the oloist for a while.
Clara-Jumi seemed perturbed at first but discipline and nerve prevailed. The bird kept flyng back into her view but she played on, pretty impressively. Watch the performance on Medici.TV here, starting at 0:52.
Maybe it was the soul of Tchaikovsky, sent by way of blessing.
