Sit Back and Enjoy a Stand-Up Performance Tonight NPR presents its first ever live classical music webcast. The Russian National Orchestra featuring pianist pianist Piotr Anderszewski and violinist Nicolai Znaider performs at the Lincoln Theater in Napa Valley. It all starts at 10 p.m. eastern, with Performance Today host, Fred Child hosting. The show is on a West Coast swing. On Thursday, Fred hosted the Emerson String Quartet, one of the world's great chamber ensembles. Fred chatted with Emerson violnist Eugene Drucker on stage at the Napa Valley Opera House about everything from the division of labor for the Beethoven quartets to the optimal position for performing. The chamber group's violinists and violist recently went from sitting down to standing up at performances. Standing apparently makes for a more compelling sound.
