Watch Cineb. In the spring of 2024, the Berliner Philharmoniker, under the direction of their chief conductor Kirill Petrenko, presented a staged production of Richard Strauss’s thrilling and dark opera Elektra – the highlight of the Baden-Baden Easter Festival. The title role was sung by the acclaimed soprano Nina Stemme. Philipp Stölzl, who has caused a sensation with his spectacular productions on the lake stage at the Bregenz Festival, was the director and set designer.
