Brilliant multi-instrumentalists S!nk host a nightly cornucopia of new music, movement and more in the world's first ever #Pianodrome. This bespoke 100-seater amphitheatre made entirely out of upcycled pianos will appear under a geodesic canopy in the verdant tranquility of the Garden. Free for all to play on, in and around during the day, and animated by night by real people doing cool stuff – you have never seen or heard anything like this before. 'Your life will be enhanced' (Max Reinhardt, BBC Radio 3).
Tickets £10-£15 from www.edfringe.com
