'Bogoroditse devo" - Rachmaninov (male choir)

A male choir rehearses Rachmaninov's movement of the Vespers down to contra G.
I recognize some members of the Male Choir of the Voronezh Philharmonic here, but I'm not sure if this is the same choir--if so, it appears it is not the full choir rehearsing. For more on the oktavist voice, visit http://www.oktavism.com
