I have long been a fan of Christa Ludwig, and these are three pieces I love. You simply cannot know how much it means that I would show her singing Brahms. Everything she sings comes from a deeper place.
My heart leaps. Doch. Die Liebe wirt's erreichen. Most rubato in Beethoven I've ever heard.
PS. You know you actually speak German when you think of a saying "doch."
