Callas's relationship with La Scala had also started to become strained after the Edinburgh incident, and this effectively severed her major ties with her artistic home. Later in 1958, Callas and Rudolf Bing were in discussion about her season at the Met. She was scheduled to perform in Verdi's "La traviata" and in "Macbeth", two very different operas which almost require totally different singers. Callas and the Met could not reach an agreement, and before the opening of "Medea" in Dallas, Bing sent a telegram to Callas terminating her contract. Headlines of "Bing Fires Callas" appeared in newspapers around the world. Nicola Rescigno later recalled, "That night, she came to the theater, looking like an empress: she wore an ermine thing that draped to the floor, and she had every piece of jewellery she ever owned. And she said, 'You all know what's happened. Tonight, for me, is a very difficult night, and I will need the help of "every" one of you.' Well, she proceeded to give a performance "Medea" that was historical."
