In page Birgit Nilsson:

"

Nilsson was known for standing up to conductors. In a 1967 rehearsal of Die Walküre with Herbert von Karajan conducting, Nilsson responded to the gloomy lighting of the production by wearing a miner's helmet (complete with Valkyrian wings).[1] When on some occasion von Karajan urged a retake "but this time with more heart. That's the place where you have your purse", Nilsson replied, "I'm so pleased to find we have something in common."[2] When Georg Solti, in Tristan und Isolde, insisted on tempos too slow for Nilsson's taste, she made the first performance even slower, inducing a change of heart in the conductor.[citation needed]
