Ansermet, Probe u. Konzert: Ravel LaValse 

The performance starts at 32:19.

07:01 😅

Wunderbar! An important historic document.

Marvelous to hear the different counterpoint moments being rehearsed without the melody. I don't think it is appreciated enough what's going on in La Valse to make it the masterpiece - and killer piece - that it is.

9:13 Simply amazing just with only brass and timpani 🌹😍

Never heard of him, but Ansermet seems a very likable guy on top of being a marvelous musician.

Elsewhere on RU-vid, you can hear Ansermet rehearse in English with Stravinsky's Firebird.

Ich wusste nicht dass Maestro Ansermet so gut deutsch konnte. Bravo!!!

36:13 classic 😅😅
