This year's festival, from May 28-June 13, featured the 18-hour Chinese opera The Peony Pavilion, a production of Bellini's I Capuleti e i Montecchi, and DJ Spooky's multimedia performance Rebirth of a Nation.
Total box office receipts were $2.53 million, a new record, and more than half of the festival's performances were sold out.
The 2005 festival is scheduled for May 27-June 12. Officials will announce the program in November.
