"There was, however, a highly important sixth figure – not a composer but a critic and, by profession, librarian: Vladimir Stasov. His was the programme of Russianizing the Russian arts, especially music and painting, freeing them from conventions inherited from Western Europe, rooting them in Russian soil – which would mean chant and folk song where music was concerned – and having them grow through treating specifically Russian subject matter".
"The kuchkists were Eurasians, who, wanting to separate Russia from everything west of the Dnieper, were happy to take its borders deep into the Caucasus and Central Asia. Turkic nomads and a heroine of Georgian legend were more acceptable than a hard-working composer-conductor whose Jewishness could be seen as allying him with the Western mainstream, and here the kuchka drew into the darker shadows of Russian anti-Semitism and imperialism”.
