The enlightenment

A concert where the classical orchestra and instruments are replaced by an electric set up. Instead of violins are neon lights, to replace drums are strobe lights and instead of clarinets we will see theatrical headlights illuminating the audience.
Through copper coils and a particular process it will be possible to extrapolate the sound of electric current going from the circuits to the lamps so giving "voice" to the electric musical instruments.
The sound of every single light will be modified in real time and summed up with all the other instruments (lighting systems) making audible the "hidden concert" of pure light.
