The Alunda Church Choir wanted to see what their giant earth phonograph, the terrafon, would sound like if they dragged it across the ground. Unsurprisingly, it sounds like dirt being ploughed. But louder.
Occasionally, nature's music of scraped soil and rocks is augmented by a loud creak from the giant gramophone horn. If you must know what that sounds like, check out the surreal 11-minute video.
The "Harvest" performance was part of the Volt Music Festival in Sweden. The group wants to bring the terrafon to other croplands soon, so if you hear what sounds like a really loud plough in your backyard, go give the team a hand. That thing looks heavy. [Create Digital Music via Inhabitat]
