Postdramatic approaches to performance and Stanislavsky's methodology seemingly occupy divergent performance traditions. Nonetheless, both traditions often require performers to mine their own lives (albeit to different ends) and operate in an experiential realm that demands responsiveness to and within the live moment of performing. Tracy Crossley explores this realm through an analysis of Quarantine Theatre's Wallflower (2015), an example of postdramatic practice that blends a poetics of failure with a psycho - physical dramaturgical approach that can be aligned with Stanislavsky's concepts of affective memory and active analysis.Wallflower provides a useful case study of practice that challenges the binary opposition between the dramatic and postdramatic prevalent in theatre and performance studies scholarship. Aspects of Stanislavsky's system, nuanced by cognitive neuroscience, can expand the theorization of postdramatic theatre, which in turn generates techniques that can prove valuable in the rehearsal of dramatic theatre itself. Tracy Crossley is a Senior Lecturer in Theatre and Performance at the University of Salford, Manchester. She is currently developing a practical handbook, Making Postdramatic Theatre, for Digital Theatre Plus.
