As of my last knowledge update in October 2023, there is no widely recognized artist named Alexander Sergeyevich Famintsin in the music industry. It is possible that he is an emerging artist or a lesser-known figure not covered extensively in mainstream music history. If you have specific details or context about his work, I could provide a more tailored response or assist you in another way. Please check for any updates or local sources that might highlight his contributions to music.
