After premiering at artsdepot back in September and making a short tour of the country, Ockham's Razor's Not Until We Are Lost returns to London for a run at Central Saint Martins' new Platform Theatre as part of the 2013 Mime Festival. Apparently inspired at its conception by the Henry David Thoreau quote 'Not until we are lost do we begin to find ourselves', the show is perhaps the most abstract the company has produced: a promenade piece that places the audience around and among a changing landscape of bespoke aerial structures, where the more literal/linear narratives from past productions are replaced by a series of vignettes testing assumptions of perspective and relation. Each performance is also accompanied by a 20-strong community choir singing an original score composed by Graham Fitkin, with harpist Ruth Wall providing live accompaniment.
