Stuart tells the audience gathered on a summer night in a church near London, ‘Tonight’s music is unique. You have not heard it anywhere before, and you will never hear it again. You may hear something extraordinary take place’. The Scrap Metal concert is the culmination of a unique Community Music Therapy project for a group of people with neurological problems, their friends and family. The audience both witness and participate in the event, which consists of prepared and spontaneous pieces improvised by an ensemble who play instruments made from things found in a scrapyard – including a car bonnet, typewriter, ‘strung sink’, bicycle wheel, and three buckets.3 And indeed the performance is unique.
