In a statement, the orchestra said that it was working with Sheng to revise the work and would reschedule its premiere.
"Bright Sheng is one of the foremost composers of our time," said music director Christoph Eschenbach. "He and I have a longtime working relationship and I hold in high regard his contributions to the music of today. I very much look forward to premiering his Concerto for Orchestra in Philadelphia as soon as possible."
Zodiac Tales was on the program for a lecture-concert on February 23, subscription concerts on February 24, 25, and 26 in Philadelphia, and a Carnegie Hall concert on February 28. It will be replaced by Beethoven's Sixth Symphony on February 23 and by Esa-Pekka Salonen's Insomnia for the subsequent dates.
