Tristan Perich’s 1-Bit Symphony is a sort of modern player piano, a microchip in a CD case that generates music.
From the video: “Though housed in a CD jewel case, 1-Bit Symphony is not a recording in the traditional sense; it literally ‘performs’ its music live when turned on. A complete electronic circuit—programmed by the artist and assembled by hand—plays the music through a headphone jack mounted into the case itself.”
The project was released in 2010.

Artwork as Recipe considers art created as formula or code which replicates by re-execution rather than playback of a recording.
