I didn’t much follow Russian dance/ballet, but no doubt there’s a strong correlation to the orchestral era. Surely Tchaikovsky would be indicative of the dance era given the related commissions.
Orlando Figes does a brilliant overview of every art form, from ballet to poetry to orchestral music to painting. Its all there. Chock full of personalities and incidents and of course, “the big picture”.
“Natasha’s Dance” is taken from a scene in “War And Peace”.
We’ll get you listen to “Rite of Spring”. Probably.
