Yi-An Xu comes in from Shanghai to conduct the Herzliya Chamber Orchestra concert Chinese Festival: East Meets West, which will feature Beethoven's 7th Symphony and two pieces of music from China. The Moon Reflected in Er-Quan by Hua Yanjun was originally written for the erhu, a traditional Chinese two-stringed violin and has been rescored for orchestra by the composer. The Yellow River is a piano concerto based upon a patriotic cantata describing the Chinese resistance to the Japanese conquest of World War II. Its character is at one and the same time lushly romantic and folkloric, based upon Chinese melodic themes and scales, much of it resembling Rachmaninoff. It is actually the only piano concerto from China which is well-known and performed worldwide. American-born, Sharon-based Nadia Weintraub (pictured) will be the piano soloist. Tuesday (January 15) and Saturday (January 19) Herzliya Performing Arts Center, 15 Jabotinsky St., Herzliya. Pre-concert lecture by Harvey Bordowitz at 8, concert at 8:30; tickets at (09) 950-0761 Weintraub also will be playing in an unusual performance of the beautiful German Requiem by Brahms, in the version for two pianos (instead of orchestra), soloists and choir, along with pianist Gaby Argov, and the Ramat Gan Chamber Choir conducted by Hana Zur, this afternoon at 2 at the Tel Aviv Museum of Art; tickets at (03) 607-7020/7000.
