He is a child out of three, "a sandwich child" and his mother is Dr. of physical chemistry in Russia, his father is engeneer.
Whether he is NP or NPA-, I really doubt the NPA=,
I do not know. I heard him playing piano on You tube and got very much interested to listen at him in concert. I am really lucky because he plays the 3rd concert of Rachmaninov -really difficult for the pianist- in Bratislava in February 2020. I will let you know what I think after this concert.
