Listening to Callas is like reading Shakespeare: you're always going to be knocked senseless by some incredible insight into humanity. She is a huge bonfire! The thread, the "inner serpent" that she would get in certain music was so complete - for example, in the Lucia recording, the phrase "Alfin, son tua." Lucia, at her absolute happiest moment, would have said to Edgardo, "I am finally yours." For me, the woman Lucia came to life in that moment, and I understood why she was out of her mind, you know? You've got it all in that one phrase.
