Want a cheap but impressive night out? Normally, the Orchestra offers $10 community rush tickets to their shows, available for one hour the night of the show, and typically not available in pairs. But thanks to a new promotion, you can score $10 tickets (pairs available) in advance to a variety of Orchestra performances throughout the spring, including this weekend’s performance with Lisa Batiashvili, the March 26th-29th performances with violin virtuoso Gil Shaham, and the April 2nd performance with Andre Previn. But you’ve got to act quickly, because the sale ends on March 22nd. To buy tickets, register here and use coupon code PECOPOWERWEEK or to avoid service charges, go directly to the box office.
