I want to know the answer to the following question:
What year was the Chopiniana released?
All the background I'm provided with is that "Sergei Diaghilev commissioned additional orchestrations—from Stravinsky, Anatoly Lyadov, Sergei Taneyev and Nikolai Tcherepnin—for later productions, which used the title Les Sylphides.". Is that enough to answer the question?
Answer: no
