Nikolai Gedda - 1980 Concert in Moscow

I think you can see Zlatopolsky at 3:53, the top center of screen, and again at 17:38-17:44. Some of the big low notes that sound like Zlatopolsky: 5:20 - Low G 7:15 - Low A 18:54 - Low A flat 38:30 low Bs and B flats 40:21 - Low B 47:27-47:42 - Down to Low G 51:10-51:30 - C#2, not super low, but really sounds like Zlatopolsky’s timbre.
