National Philharmonic and guest soloist Haochen Zhang enchant

The hardy souls who braved the frigid elements Saturday night to hear music from Imperial Russia at Strathmore were rewarded with as fine a concert, I wager, as has been heard in or around Washington this season. The perpetrators were the National Philharmonic, conducted by its music director, Piotr Gajewski, and the evening's guest soloist, Shanghai-born pianist Haochen Zhang.
