Salzburg Festival, 2003, conducted by N. Harnoncourt. This is Sesto's desperate rondo from the end of Act II. Vesselina Kasarova is not only a fabulous singer, but also an amazing actress. Her deceptively joyful "Tanto affanno soffre un core" with this painful smile just breaks my heart. Man, I actually cried over an opera!
