Mid Pennine Arts | Panopticons - Singing Ringing Tree. "The Singing Ringing Tree is aptly named. A 3-meter-tall, wind-powered musical sculpture made of galvanized steel pipes, it stands high above the English town of Burnley, Lancashire. The pipes swirl to form the shape of a tree bent and blown by the wind, and produce an eerie, melodious hum as the constant wind on Crown Point drifts through them."
