At Crown Point high above Burnley town UK the ‘Singing-Ringing Tree’ — a unique musical sculpture in the form of a tree appears to bend against the endless winds that pass over the hills. Designed by award-winning architects Tonkin-Liu. The wind produces a low and mellow hum through pipes which are tuned so that they do not disturb the wildlife.

It was designed as one of four large-scale sculptures commissioned, designed and constructed over a six year period in the North West of England.

It involved the construction of series of 21st-century landmarks, or Panopticons (structures providing a comprehensive view), across East Lancashire, England, as symbols of the renaissance of the area. An interesting article by the independent newspaper can be found here.
