This is what you get when you create art and music...
An Anarchestra is an orchestra of over two hundred unique musical instruments built (with a few exceptions) by Andy Thurlow and Alex Ferris, an American musician, composer, and theorist.
These instruments have been created to explore alternative timbres, tunings, and methods of playing, and are set up as an interactive art installation that the public gets to play. These instruments can be tuned all to the same key making it hard to hit the wrong notes.
You don't have to be a good musician to play these!
