The Philadelphia Orchestra is about to embark on a massive three-week tour of the Far East, and there’s little question that they’re going all out to impress the concertgoers of South Korea, Japan, China, Singapore, Hong Kong, and Taiwan. Superstar soloists Yo-Yo Ma and Lang Lang will be the featured attractions, and an exhausting set of three complete Mahler symphonies will form the backbone of the tour repertoire, as well as the core of a live-to-tape recording the orchestra intends to release after the tour from concert tapes taken in Tokyo. The cost of the tour, large even by major orchestra standards, is $3 million.
