The Jerusalem Symphony Orchestra is in the middle of a 20-concert tour of the United States, which began last week in Orlando. The Orchestra is scheduled to perform along the East Coast. Some travel plans were changed with the blizzards and snow that hit the northeast, but the 90 musicians made it to their destinations. They will be performing works by Hindemith, Copland, Shostakovich, Prokofiev and Strauss before crowds at Carnegie Hall in New York City and the Israeli Ambassador in Washington D.C.
