"Unter Donner" Kleiber rehearsal

This is a rare video of a Carlos Kleiber rehearsal. There are a few others, including the maestro camera in the opera pit and the famous 1970 video of the rehearsal and performance with the Sudfunk Symphony Orchestra. This is a small window into the rehearsal process of one of the great conductors.

Kleiber rehearsal with Vienna Philharmonic

A few thoughts

1. Kleiber doesn't conduct from the score and only opens it up with reluctance
2. He sings the percussion part: note how he sings it and how it sounds in the final performance! 
1. If you hear the performance and sing it to yourself after, that's how it sounds!
3. Even the Vienna Philharmonic can be unprepared! 
4. The Vienna Philharmonic doesn't sound special -- note the difference between this and the performance! 

Performance in 1992 New Year's Concert

Performance by Bavarian State Orchestra on tour in Japan  in 1986

I think this performance is superior to the Vienna one above. Many of the gestures are the same but the orchestra realizes them more clearly and exuberantly.
