One of a group known as "The Five" of great composers to come out of Russia on the latter part of the 19th Century (along with Alexander Borodin, Modest Moussorgsky,et al) Nicolai Rimsky Korsakov (1841-1908) was initially a naval officer who became an inspector general of Russian Naval bands and later a professor of music at the St. Petersburg Conservatory of Music.
This selection of music is from a ballet opera called "Mlada" (1890) , a work spawned from tales of Russian folklore that concerned murder, revenge, romance and the supernatural.
During the 1905 Revolution, he, like many left-leaning intellectuals, supported the students at St. Petersburg University and other activists in their demands for a reformed curriculum and a national Duma (legislature) to check the powers of the Czar and his ministers. The reactionary authorities got him fired from his professorship and 300 student-activists leaders dismissed.
But so great was the outrage and so intense was the overall General Strike that crippled urban Russia in late 1905 that Professor Rimsky-Korsakov was restored to his university and the people got their National "Duma".
