Hey there!
I don't know if you folks are interested in this, but It's very interesting.
Even if you aren't interested in history, you should look here:
www.sovmusic.ru ( if you don't know russian, click on English on the right )
I found this some time ago.
Man, I like this music. Not because of the ideology, just because it's very good music. I love to listen to it, so I considered it relevant to post, because some other people may like it too.
