Piano Tree

California state University, Monterey Bay  "Piano Tree"  in a forested area on their Disc Golf course.  A living installation by artist Jeff Mifflin.

Although the piano itself is believed to be just a stage prop which was cut apart then placed around the tree behind the California State University music department by artist Jeff Mifflin, the tree carried on growing and parting the timber of the piano for some time until a drunkard decided to smash it up.
