Eastley’s installation involves eight lightweight Aeolian harps mounted on the roof of Perrott’s Folly. The sound made by wind blowing through the harps is amplified and fed to loudspeakers at lower levels to combine with the sounds emanating from a number of acoustic sculptures, transforming the interior of the tower into an immersive aural experience.
