Finding the identity of pianist(s)

Who is this piano man? I do not think anyone would try to pretend this type of illness to get publicity.

It is sad that the piano man can only find his peace at the piano. I don’t know what kind of trauma or experiences he had to cause his anxiety. Talking about finding his identity, maybe finding his social identity is not so important if he can only keep his real artistic identity in this stage of mind. It is hard enough to find one’s own identity in this world. True artistic identities are almost non existent in the classical music world. They are either killed by the competitions or by the society.
