This is a very recent performance in Baden-Baden.
I'm not a Renee detractor per se, although I question some rep choices she has made over the years. Even as a woman "of a certain age" she makes really glorious sounds. In this video, my questions are about some of the apparently arbitrary acting movements ("OK, this is where I make the cross", "OK, this is where I turn back to the audience because I'm going to sing at them in a moment"). Usually that is not my experience with dear Renee's acting.
I will include some videos of other renowned Ariadnes, not for Renee-bashing--this is a bash-free blog--but for added insight.
