This article considers two examples of life story performance: the first autobiographical work about the author's recovery from stroke, and the second the life-story production Re-Live Theatre's "Memoria" about dementia. It explores how performing life stories facilitates connection between performers with transformed cognitive capacities and their audiences, and posits that life-story performance offers a unique way to affect relations between performers and their audiences through an experience of 'felt resonance'. The article argues that felt resonance in performance matters: it leads to possibilities of transformative connections within and between bodies, as well as the systems that they are part of.
