Recommend Outstanding Russian Choral Music

" Any Sviridov choral music will put you in tears" Did the KGB use this during torture sessions?
BTW, most of the older posts have been deactivated (links don't work).
Also, the "Feodor Potorjinsky's Russian Choir Vespers and Matins" does not appear to be on CD only vinyl. 
I'll look into @mahgister suggestion ASAP.
Have you heard : Szymanowski & Poulenc: Stabat Maters by Shaw/ASO/Chorus (2006-07-09)?
Plenty of good choral and I think one guy has your "Octavist" voice.

This is the best of modern times by perhaps the Greatest Russian composer of modern times .

All of these recommendations are surely great.
I was hoping for something from a military choir 100-200 men?
Hits you like a tsunami...
Anything recorded?
Check out "The Peacemaker" movie for an example.
Thanks to all

This is the Red Army Choir , The best military choir there ever was or ever will be .

It came from the Red Army, the most powerful army the world has ever
seen which did the heavy lifting that defeated the mighty German
Army in WW II.
Believe it or not, the Brave American , British and Canadian soldiers
who fought and died on D-Day did so on a day not in the top 20
battles between Russia and Germany .

This choir is so strong because it sings for a least 6 million Russian Soldiers who died .
To Russia WW II will never end .
