Party like it’s 2019! The orchestra’s music director Thomas Dausgaard has laid on Stravinsky’s Firebird Suite as the pièce de résistance of the main event, but the festivities don’t begin and end there. The preceding cocktail hour features “immersive” serenading, and there’s a formal dinner to follow, with eats from the celebrity chef Kristi Brown of Communion and That Brown Girl Cooks. Proof of vaccination “requested.” —M.G.
