“It’s for this reason that the other big star of the show was the Washington National Opera Orchestra under conductor Evan Rogister, who led a performance that managed to sound appropriately untethered and deceptively exacting. I tend to groan about the volume in this hall, but even at this reduced orchestration of “Elektra” (85 musicians as opposed to the 113 called for by Strauss), the sound was vibrant and rich. Rogister’s steering of the music’s violent weather had me loosening my tie, and his finely attuned management of its mess of motivic gestures and granular details was superb.”
