Play Me, I’m Yours is street art by Luke Jerram that’s going on right now on in New York City and London: 60 pianos in New York, 21 in London, available for members of the public to play. (It was in London last year, as well as a few other cities since 2008.) As a concept it’s neat, but I can’t help but wonder whether, outside artistic centres like New York and London, you wouldn’t end up with one version of “Heart and Soul” after another.
