Dostoyno Yest - Everyday Choir of the Holy Trinity St. Sergius Lavra 

Divine perfection of powerfull feelings expressed in sound! It just makes you want to kneel... strong bass section, with dedicated tenors and baritones to hold the hars harmony in place....simple, touching, breathtaking piece!

This is the best choir I have ever heard

At 0:35 there is a closeup of the bass section of the choir. First on the right hand side is deacon Nikolai Platonov, a well-known bass. However I am not sure if he is an oktavist.
