Russia in prog

(i apologize beforehand if this was brought up earlier)

a simple thought crossed my mind with a chainsaw. just a
modest impulse for wondering: what if...
What if Russia had its true prog band... I'm talking about seventies, about the golden age.
I came to think of it after listening to Italian prog, which is mostly sypmhonic; i started to consider their classical music roots (Verdi, Rossini). Then i turned to germany and their traditions (Brahms, Beethoven). Finally, eventually and inevitably i remembered Tchaikovsky, Shostakovich, Rachmaninov, Prokofiev, etc. a musically rich country supressed by politcal circumstances. what could have been?...

and the second part: what is Russia worth in prog?
do they have any prog history and what can be said about it?
