Last year a bunch of pianos were set up around New York City's parks and streets, allowing any passerby to bang away at the keys. And now they're back! Starting this Saturday (through July 2nd), 88 uprights will be available in all five boroughs, that's 28 more than last year. They will all be adorned by artists—including a colorful knit one that will be placed under the Manhattan Bridge archway—and you can find out where they'll all be on this map. While it's endless fun to hear strangers practice chopsticks, what if some famous faces showed up? Click through for who we'd like to see take a seat at one of these.
