Behold: a video recording of  the first ever composition for The Great Stalacpipe Organ, the largest musical instrument in the world. Located deep in the caverns of Luray, Virginia, The Organ consists of hand-tuned ancient stalactites of varying sizes that are hit with solenoid-actuated rubber mallets. It took Pepe Deluxé over 6 years of research and planning so you could enjoy these two minutes of unique sounds in the comfort of your bright, dry, warm home.
