A rock band consisting of electromechanical instruments that makes music by throwing rocks through the air, slapping them and making them vibrate. The project by Los Angeles-based artist Neil Mendoza is controlled by a computer running a MIDI player while playing Here Comes the Sun, a biographical song describing the daily experience of a rock sitting on the ground.
The rock band consists of the following:
- Pinger fires small rocks at aluminium keys using solenoids.
- Spinner launches magnetic rocks, Hematite, at pieces of marble. Rocks are launched by spinning magnets using Applied Motion stepper motors.
- Slapper slaps rocks with fake leather.
- Buzzer vibrates the plunger or a solenoid against a piece of marble.
