As born & raised in ex-USSR... West music didn’t turn youth against USSR. Rebelling youth just used West music as a tool to show off. It was same rebellion as in West or at any point in history. Youth against stupid rules imposed by elders. It was just completely opposite politically compared to West counterparts at the time.

But that bit show author’s bias very well. As ex-USSR metal head, visiting West festivals was complete culture shock how different attitude is. Yet the spirit is very similar.
