On Tuesday, the Kennedy Center, which has been experimenting with the rollout of its season announcements for the past couple of years, announced, without a news conference or fanfare, the 2018-2019 seasons of its classical music constituents: the National Symphony Orchestra, the Washington National Opera and the Fortas Chamber Music Concerts.

The NSO continues to feel what one might term the Gianandrea Noseda effect, with a new level of offerings and programming in the second season of its new music director. Britten’s War Requiem with Karina Flores, Ian Bostridge and Matthias Goerne.
