This article examines the dramaturgy of light, addressing ways in which its ephemeral, spatiotemporal materiality may be understood as a crucial infrastructure of performance. Graham propose that ideas of new and expanded dramaturgies provide a productive frame with which to explore the generative impact of light on performance. She argues that examining ways in which light operates within performance provide a fruitful means of analysing the dramaturgical structure of a work. She demonstrates ways that light sculpts both the form and the content of a specific example, the recent contemporary dance work *Both, and* by the Russell Maliphant Company, and use this analysis to offer insight into the dramaturgical potential of scenographic light more broadly.
