I just watched and listened to the whole performance. One of Strauss's greatest works in a thrilling performance.
I heard Thielemann conduct Rosenkavlalier in London three times in 2002, I believe. And at a reception for a not too good performance of Dutchman during that time, I spoke to members of the Covent Garden Opera orchestra. One violinist said he thought Thielemann was as fine as Carlos Kleiber. I'm not quite willing to go that far, but at his best and in his repertoire, Thielemann is one of the finest conductors in the world today.
Maybe he will find his way to more Mahler. But his Strauss and Wagner are marvelous and maybe his Bruckner.
On the video you can see and hear how the Vienna Phil really plays for him, fervently.
Best to all,
