No reason given (just watch the nightly news).
Here’s the Tangle’d version:
The Hong Kong Chinese Orchestra has canceled its two U.S. tour engagements, including its scheduled performance at Tanglewood on Wednesday, August 21. The new program for that day will be Tan Dun’s Martial Arts Sonata Trilogy, an evening of chamber works by Tan Dun, the world-renowned artist and UNESCO Global Goodwill Ambassador. Inspired by the music from Mr. Dun’s acclaimed film scores to Hero and Crouching Tiger, Hidden Dragon, the concert will also feature video excerpts from these award-winning movies. Artists for the evening include Magdalena Baczewska, piano.
