At the end of July, John Richards took his Dirty Electronics project to the Dartington Summer School in Devon. Attendees built and played what Richards calls a Faraday Dirty Kinetic Generator (as well as other instruments).
The Faraday Dirty Kinetic Generator charges a capacitor as the tube is shaken and sounds a note. Once each capacitor is fully charged, the players are given a cue to stop shaking, and a continuous tone will sound. The unified single pitch will gradually fragment into downward glissandi and an evolving cluster chord as the capacitors discharge. The instrument building workshop culminated in a performance, which took place 3 August in Dartington's Great Hall.
Andrew Hill filmed and edited a documentary on the summer school, watch it below.
