46 street pianos, decorated by artists and groups, were placed across the entire city from 25 June to 9 July 2013 for people to play and enjoy. During this two week period 40 micro-concerts were played by amateur and professional musicians. Following the event, the pianos were offered to non-profit organisations, schools and hospitals.
