During an electronic music performance it is common to see light and sound interacting electronically in many different ways. From sound and light shows, whereby light reacts to sound, or generated visuals are projected onto a screen behind the performer. However we asked the question what if we could convert sound to light and back again and control sound with light? Inspired by the huge acoustic of the Mimerlaven at Norberg festival we built a `light instrument' that allowed us to interrupt and disrupt sound using light forming the basis of our piece `Interruption'.
