My dad listens to BBC Radio here in Houston every day on the way to work. And I heard about these pianos in London by an artist named Luke Jerram. He has peppered 30 pianos around London for people to play with the words ‘play me, i’m yours’!
Unfortunately I am here in Houston while this is going on! It sounds beautiful on the radio! please go visit!
Here is the site about the project
And about the artist
