I once tried to figure out the soviet equivalent to Video Killed the Radio Star. At the time I thought it had a definite answer (involving people in golden lamé bouncing on trampolines?), but can't seem to re-search it now.
Taking "music video" to be an edited video with footage distinct from a studio performance, and not part of a larger work (to avoid musicals), I find
Afaik Soviet ‘estrada’ had lots of videos filmed like they're concert performances but made specifically for TV. With characteristic mannequin stage presence of the artists, the ‘singing hand’, and backing ‘bands’ wriggling incoherently, hands flopping around on the instruments. And no audience shown.
The only thing this mess could kill is my will to listen to anything until Western electronic and grunge stuff finally became widely available.
(singing hand? I'm getting some cool ionophone stuff, as well as a seductive western agent with wardrobe malfunction, but I doubt either of those were the reference... In other news, TIL the russian sign language for "officer" mimes epaulettes. I wonder how the plural is conveyed, maybe duplication?)
So I guess it doesn't conform to the criteria for your previous search. But the film supplies material if you have similar collections for other architecture.
The ‘singing hand’ is a term for how the microphone-free hand often was the most animated part of a Soviet singer, being waved around while the rest stays in place.
BTW, the Russian spelling is “эстрада” (you won't need “музыка” since that's the primary meaning). Unless you had some other Cyrillic spelling in mind. The videos in your previous search have “эстрада80” as a hashtag.
P.S. The real impressive part in ‘Marian the Librarian’ is whatever the hell is going on with everyone's hair.
Thanks for the clarifications[1], and sorry I'm not counting that clip[2] in my head-canon, otherwise I'd have to count just about every number from every Blue Light special.
Is the hair much different from https://www.youtube.com/watch?v=F6bRxLzFLv0 ? (it appears that costume musical comedy often tells us almost as much as the era in which it was filmed as the era which it depicts)
I also have to disqualify the following. It's single take and could have been stage business. But still, it's almost a music video, and judging from the comments, was televised in the late 70's.
