Interesting that you chose a Celibidache recording of Brahmsâ Fourth Symphony. I have it, but almost always default to the C Kleber Wiener Philharmoniker recording.
I read some time ago that Celibidache and Kleiber strongly disliked each other when they both had conducting posts in Munich - poison pen letters in the local press, etc. Two very different personalities, I suppose, with each wanting to be top dog.
