Soprano Nina Stemme brought down the house when she headlined the premiere of visionary director Patrice Chéreau’s 2016 staging of Elektra. Now she returns to Strauss’ unhinged heroine, opposite one of today’s most in-demand artists, soprano Lise Davidsen, as her sister, Chrysothemis. Donald Runnicles is on the podium for one of opera’s most blistering scores, leading a cast that also includes mezzo-soprano Michaela Schuster as Klytämnestra, tenor Stefan Vinke as Aegisth, and bass-baritone Greer Grimsley as Orest.
