This edition features the work of 10 artists from the UK and Lebanon who explored the sound environments, acoustic potentialities and aural histories of two cities, London and Beirut. This edition is a collaboration between Institute for Global Prosperity UCL, Recomposing the City, RELIEF Centre, Optophono and Theatrum Mundi.

Optophono was established in 2013 as a music label that goes beyond fixed recordings. Instead of publishing fixed media such as CDs or DVDs, they make interactive editions that they print on external drives and USBs. Optophono is currently based in Oxford, England.
