I found info about the 88 pianos when I was searching the origins of this piano (but not the NYT story -- thanks!). I didn't know about that project, but I'm fairly sure this one did not come from that source. It's on a little beach where people aren't supposed to go, and it's not painted as the 88 pianos were. Well, it wasn't painted initially -- by now it has graffiti, and someone brought the piano flowers.

There have been news stories speculating that the piano was placed under the bridge for the video shoot -- which I assume would be illegal. The person who made the video put the Vimeo link in the comments on my Youtube video -- but then the link disappeared. Maybe he feared legal action?
