Darth Vader masks compose a dark symphony

This project called "Last Manoeuvres in the Dark" by artists Fabien Giraud and Raphael Siboni currently on display in Paris at the Palais de Tokyo, employs hundreds of Darth Vader masks equipped with microcontrollers and speakers and connected to a computer which spatially composes one of the "darkest" musical pieces of all time. This video illustrates the performance pretty well.
