Just like the plastic characters in Toy Story, the players in the National Symphony Orchestra appear slightly rigid on stage. But while the toys on screen move that way as a joke, the musicians gesture precisely to play their instruments with practiced skill. Led by Emil de Cou, who’s hailed by the Washington Post as “one of the few conductors trying to open new doors into classical music,” the orchestra will loosen up and churn out familiar scores culled from more than a dozen Pixar films, including The Incredibles, Cars, Brave, and the Toy Story series. And while the NSO fills the space with recognizable tunes, a screen behind the orchestra will broadcast the equally memorable scenes from the respective films. The program’s not just for kids. This is critically acclaimed music: Collectively, the Pixar film scores featured in the show have won three Academy Awards and 10 Grammys. Still, it’s OK if you let your inner child out to play for this one. We won’t tell. The National Symphony Orchestra performs at 8:30 p.m. at the Filene Center at Wolf Trap, 1645 Trap Road, Vienna. $30–$58. (703) 255-2900. wolftrap.org.
