(My understanding of Site-Specific Performance after reading Mike Pearson’s “Site-Specific Performance”, Introduction.)

Site-specific Performance Definition: performance generated from or for a selected site
‘Layers of the site are revealed through reference to historical documentation, site usage (past/present), text, sound, personal associations, half-truths, lies.’ (Wilkie, 2002a, 150, as cited in Pearson, 2010, 8)
Part of the work has to do with researching a place and its history, then inserting a classical or modern text in to this ‘found space’ which then throws a new light on it.

Pervasive media is new types of digital media linked to an awareness of place and location. It is delivered in to the fabric of everyday life. (Watershed, 2015)
