most famous not just because of his talent as a musician, but he uses his fame in Russia to promote artists (vocalists, writers and more) their talents

He promoted this guy - though from Kazakhstan he has gone all in with Dimash Kudiabergen
I think is the greatest vocalist ever to have lived.
You can see Krutoy at the piano in this too.
