Suggestions for Russian chorus film scores

Some examples:

Hymn to The Hunt for Red October
Basil Poledouris – Hymn To Red October – YouTube (http://www.youtube.com/watch?v=rPsL2WVhFCc)

Song of the Plains (Used in Castaway)
Soviet Army Chorus & Band – Song of the plains – YouTube (http://www.youtube.com/watch?v=5hliuEte028)

Kremlin with Anticipation (M:I 4)
Mission: Impossible Ghost Protocol Soundtrack – Kremlin With Anticipation – YouTube (http://www.youtube.com/watch?v=SXSo1JhWE68)

Between these three tracks, you can see what I am looking for. Any recommendations or suggestions would be highly appreciated.

Thanks.

Also the Mask of the Phantasm theme: Batman Mask of The Phantasm Theme – YouTube (http://www.youtube.com/watch?v=TOSS-ZFDMo4)
There is a similarity with the Hymn of the Red October, yet that doesn’t change a bit of the fondness i have with this score in particular.
