“Darkness is made when light flickers”. (Derek Jarman quoting Aristotle, in Chroma - a book of colours ). In a thunderstorm, there is lightning (the light), thunder (the sound). The distance between the lightning and the thunder determines the distance to the danger. The film is made up of scattered photograms of light - captured on the fly during a thunderstorm - black leader and lots and lots of tape. Each tape activates the projector’s loop regulator, a sound synonymous with potential danger for any discerning ear. A fragile single copy, it gets damaged with each pass. One day it will be not possible to project it anymore.
