Where can i find soundtracks rips of the Russian composer Alexey Rybnikov, is there any special post here about him?

Maybe I can help you. Rybnikov have a huge composer's discography. What albums are you intresting in?
I have a boxset, at my collection, ''Film Music'' (5CD, Flac) - with a lot of his score and songs (written, not performed).
This one, probably, the best of. I can upload it.

Yes please upload it, any OST of him is new to me, i listened to some tracks on youtube from the 70s and liked his music, would like to know him more if possible..
