He can barely play keyboard, let alone anything else.
Like everything else, he vastly over rates his skill level with musical ability, both playing and writing. If he were 10 years old and still in lessons to learn piano it would be cute.
Even if he had the knowledge behind him he’s missing the talent and I believe his fucked up fingers make playing properly impossible. One thing that fascinates me is how hard he hammers the keys, you can hear the mechanics of the keys being hit over any melody he’s trying to play.
He’s just shit at everything.
