Ok?! This instrument is called an Electone and you can virtually play a whole orchestra on it. Wow.
Playing it is very difficult as you have to use your hands and feet at the same time playing notes, using pedals and switching instruments.

This crazy dinosaur may seem a little bit “whut?” but wait till he starts playing! This is awesome!

Ok, this is one of those video’s you genuinely go “WTF?!?!”. Weird stuff over there in Japan
