I meant to say the feeling/mood of the music in the clip came to me as "very Russian", like as if the composer was wanting to express something "very Russian" in its emotions. That it was a "powerful"/sentimental piece of Russian music. I didn't understand the words but I sensed it was emotionally attached to Russia.
You are very right, Harpsi, but many people were against him because he also composed a bit more complicated music, he thought that Stalin liked hime, they were from the same village, but Stalin liked nobody...
Nowadays is difficult or impossible to get his music. The guy was very communist indeed.
