@StanleyPiano, the world's first interactive player piano, makes his worldwide debut at Seattle's Capitol Hill Block Party. Stanley is a precocious instrument who takes song requests via Twitter. Stanley can play a lot of songs, but he loves indie music. He even went out of his way to learn a song for each of the bands playing at the Block Party. Stanley bares all as his moving parts (gears, bellows, hammers, valves) visibly work as the keys press themselves.
