The speaking voice of Mikhail Zlatopolsky.
Zlatopolsky had an enormous voice and was extraordinary in the realm of bass singing. Mikhail also held the Guinness World Record for being the lowest bass in the world at one point. He also possessed incredible power and resonance. There are anecdotes stating that he shook the bodies of the other choristers when he sang in the contra octave.
