As the closing notes of Salome echoed throughout Symphony Hall in March, the audience rose to its feet in a roaring standing ovation. If you’ve ever been to the symphony, you know that means something—this can be a bit of a reserved crowd. Undeniably one of the most exciting musical events of the year, the one-night-only production of Strauss’ interpretation of Oscar Wilde’s take on the biblical tale marked BSO music director designate Andris Nelsons’ first time conducting opera at Symphony Hall—and only left us more excited for his debut season, which kicks off in September.
