Yuri Vishnyakov (or Wichniakov) is one of the more well known Russian basso profondos, although there are relatively few videos of him singing. Vishnyakov is perhaps responsible for popularizing the Russian basso profondo as he is featured on the Orthodox Singers CD "Basso Profondo from Old Russia."
Vishnyakov, along with Boris Tchepikov, and Viktor Krutchenkov, sung perhaps the most impressive rendition of Chesnokov's "Do Not Reject Me in My Old Age," a piece for a basso profondo soloist, although, in this case, three basso profondos sing!
You can hear the recording below:
Vishnyakov hits a rather impressive G1 at the end, although it is somewhat masked by the G2 sung by the other two bassos. Vishnyakov has performed with a number of Russian Choirs. He recently has performed with the Orthodox Singers choir, but he can be seen here performing the Russian Patriarchate Choir of Moscow:
In a more recent video, we have Vishnyakov singing with the Orthodox Singers, performing the entering chant "It is Fitting" :
