Swiss pianist Gabriel Arnold plays piano on sea of ice!
Have you ever seen a man play the piano on frozen sea, in front of a really big ship?
If the answer to that is 'No'... don't worry, Newsround has you covered!
This is Gabriel Arnold and he is a famous pianist from Switzerland.
Gabriel has performed in lots of what he calls "special places" such as the Swiss Alps and even from the top of the Seven Sisters cliffs here in England.
His latest unforgettable location is the frozen surface of the Baltic Sea.
Some tourists were lucky enough to hear it from the deck of an ice-breaking ship.
He should have played some music from Frozen!
