Peterloo 5.1 is a sound composition inspired by a historical event that came to be known as 'The Peterloo Massacre', that happened in Manchester, England on the 16th August, 1819. The sound material consists of location recordings captured from recent student protests held in Manchester 2010 and the rural setting of Maccelesfield Forest, Cheshire in 2010. Historical transcriptions and archive sound recordings were gathered with the help of Prof. Robert Poole of the University of Central Lancashire, The Peoples Museum, Manchester, The North West Sound Archive and the British Library. The text transcriptions provided a narrative framework to structure the electroacousitc sounds. The soundscape recordings were sonically transformed using a computer and spatially arranged within a 5.1 loud speaker array. The spatial aspect of the composition considers the listeners position, reception and inclusion.
