"Tu che di gel sei cinta"

Renata Tebaldi singing Liu's aria from the second act of Giuseppe Puccini's opera Turandot. The slave Liu is being tortured to give her owner's name, but she resists, even as the crowd around her screams for her to speak and give up the name. In the end, she grabs a nearby knife and stabs herself, as the crowd continues to scream for her to reveal her secret.

"Parla! Parla! Parla!
Il nome! Il nome!"

Despite its grisly ending and subject matter, this is one of the world's most beautiful and recorded arias.
