Lehman Center for the Performing Arts welcomes the China National Symphony Orchestra to the stage. For nearly half a century, the CNSO has entertained audiences in China and worldwide with a vast repertoire of classical, romantic, modern and contemporary orchestral works by both Western and Asian composers. They’ve collaborated with such world-class artists as Isaac Stern, Yo-Yo Ma and Lang Lang. Now, they return to the United States with a program featuring Xia Guan’s Requiem for the Earth, 1st Movement; Tchaikovsky’s Piano Concerto No. 1 and Beethoven’s Symphony No. 7.
