By Syd Klinge and displayed at Coachella 2010. As notes are played on the keyboard a high voltage arc is ignited which climbs up individual jacob's ladders built within the pipes. This creates both the sound of the organ and a visual spectacle as well. Each note is tuned to a specific pipe and each one has a ton of transformers inside.
To hear original audio from the organ please select the video entitled "The Pipes - Audience Participation"
