This week on Sinica, on the occasion of the 50th anniversary of the 1950 concert tour of China by the Philadelphia Orchestra in 1973, Kaiser chats with Matías Tarnopolsky, Alison Friedman, and Wu Fei about the legacy of the Philadelphia Orchestra’s China tour, their continuing connection with China, and their concert performances in Chapel Hill, performed to the day on the two closing nights of that historic tour 50 years ago.
