Tangent is a task-based performance that assesses the perfection of a circle drawn by hand, using geometric processes to create a graphical representation of error. Gillian’s ability to perform perfectly is inextricably bound to the perfection of the circles she draws. Each circle is geometrically assessed, creating a graphical display of any deviation from perfection, both in terms of the circle and Gillian’s ability to perform.

Inspired by the development of Third Angel’s 9 Billion Miles from Home and A Perfect Circle by Christopher Hall, Gillian Lees and Alexander Kelly, Tangent is an ongoing inquiry as to the nature of perfection in performance.
