Offering fresh studies of Samuel Beckett in pre-production, in rehearsal, as an innovator of the script form, and as a speculative director and designer, Beckett’s Laboratory reconsiders Beckett’s stringent approach to stage direction through the lens of the laboratory and reveals his experimentalism with stage representation and composition. Wakeling argues that acknowledging Beckett’s experimental processes, from their composition to their reception, is crucial to understanding the innovative representations of humanity that emerged at different stages in Beckett’s practice.Repositioning Beckett’s performance oeuvre in relation to philosophy, Wakeling draws upon post-dramatic, symbolist, materialist and post-structural understandings of theatre performance to reappraise Beckett’s plays as a composition for performance. The philosophical underpinnings of Beckett’s practices are explored through an eclectic mix of familiar and unexplored contemporary theatre productions and films o

The gods have much to tell us about performance. When human actors portray deities onstage, such divine epiphanies reveal not only the complexities of mortals playing gods but also the nature of theatrical spectacle itself. The very impossibility of rendering the gods in all their divine splendor in a truly convincing way lies at the intersection of divine power and the power of the theater. This book pursues these dynamics on the stages of ancient Athens and Rome as well on those of Renaissance England to shed new light on theatrical performance. The authors reveal how gods appear onstage both to astound and to dramatize the very machinations by which theatrical performance operates. Offering an array of case studies featuring both canonical and lesser-studied texts, this volume discusses work of Aeschylus, Sophocles, Euripides, Aristophanes, and Plautus as well as Beaumont, Heywood, Jonson, Marlowe, and Shakespeare.This book uniquely brings together the joint perspectives of two expe

This is the first full-length book to provide an introduction to badhai performances throughout South Asia, examining their characteristics and relationships to differing contexts in Bangladesh, India, and Pakistan. Badhai’s repertoires of songs, dances, prayers, and comic repartee are performed by socially marginalised hijra , khwaja sira , and trans communities. They commemorate weddings, births and other celebratory heteronormative events. The form is improvisational and responds to particular contexts, but also moves across borders. For students of theatre and performance, anthropology, religion, gender and cultural studies, this book illuminates an important form of performance, considering its changing status and uncertain futures.The book draws from anthropology, theatre and performance studies, music and sound studies, ethnomusicology, queer and transgender studies, and sustained ethnographic fieldwork to examine badhai ’s place-based dynamics, transcultural features, and

The crafts of governance and diplomacy are spectacular, theatrical, and performative. Performing Statecraft investigates the performances of states, their leaders, and their citizens on an expanded field of the global arts of statecraft to consider the role of performance in the domestic and international affairs of states, and the interventions into global politics by artists, scholars, and activists. Treating theatre as both an art form and a practice of political actors, this book draws together scholarship on the embodied dimensions of governance, the stagecraft of revolution, arts activism on the world stage, sports performance by heads of state, the performativity of national dress, speechmaking and colonialism, war and medicine, singing diplomats, indigenous sovereignties, and performed nationalisms. It brings the perspective and methods of performance studies to bear on global politics, offering exciting new insights into encounters between states, sovereigns, and people.

In the early eighteenth century, the benefit performance became an essential component of commercial music-making in Britain. Benefits, adapted from the spoken theatre, provided a new model from which instrumentalists, singers, and composers could reap financial and professional rewards. Benefits could be given as theatre pieces, concerts, or opera performances for the benefit of individual performers; or in aid of specific organizations. The benefit changed Britain's musico-theatrical landscape during this time and these special performances became a prototype for similar types of events in other European and American cities. Indeed, the charity benefit became a musical phenomenon in its own right, leading, for example, to the lasting success of Handel's Messiah. By examining benefits from a musical perspective - including performers, audiences, and institutions - the twelve chapters in this collection present the first study of the various ways in which music became associated with t

Music, Dance, and Drama in Early Modern English Schools is the first book to systematically analyze the role that the performing arts played in English schools after the Reformation. Although the material record is riddled with gaps, Amanda Eubanks Winkler sheds light on the subject through an innovative methodology that combines rigorous archival research with phenomenological and performance studies approaches. She organizes her study around a series of performance-based questions that demonstrate how the schoolroom intersected with the church, the court, the domicile, the concert room, and the professional theater, which allows her to provide fresh perspectives on well-known canonical operas performed by children, as well as lesser-known works. Eubanks Winkler also interrogates the notion that performance is ephemeral, as she considers how scores and playtexts serve as a conduit between past and present, and demonstrates the ways in which pedagogical performance is passed down throu

During the 1820s, British society saw transformations in technology, mobility, and consumerism that accelerated the spread of information. This timely study reveals how bestselling literature, popular theatre, and periodical journalism self-consciously experimented with new media. It presents an age preoccupied with improvisation and speculation – a mode of behaviour that dominated financial and literary markets, generating reflections on risk, agency, and the importance of public opinion. Print and Performance in the 1820s interprets a rich constellation of fictional texts and theatrical productions that gained popularity among middle-class metropolitan audiences through experiments with intersecting fantasy worlds and acutely described real worlds. Providing new contexts for figures such as Byron and Scott, and recovering the work of lesser-known contemporaries including Charles Mathews' character impersonations and the performances of celebrity improvvisatore Tommaso Sgricci, Angela

Until now, biological invasions have been conceptualised and studied mainly as a linear process: from introduction to establishment to spread. This volume charts a new course for the field, drawing on key developments in network ecology and complexity science. It defines an agenda for Invasion Science 2.0 by providing new framings and classification of research topics and by offering tentative solutions to vexing problems. In particular, it conceptualises a transformative ecosystem as an open adaptive network with critical transitions and turnover, with resident species heuristically learning and fine-tuning their niches and roles in a multiplayer eco-evolutionary game. It erects signposts pertaining to network interactions, structures, stability, dynamics, scaling, and invasibility. It is not a recipe book or a road map, but an atlas of possibilities: a 'hitchhiker's guide'.

Scholars of early Christian literature acknowledge that oral traditions lie behind the New Testament gospels. While the concept of orality is widely accepted, it has not resulted in a corresponding effort to understand the reception of the gospels within their oral milieu. In this book, Kelly Iverson reconsiders the experiential context in which early Christian literature was received and interpreted. He argues that reading and performance are distinguishable media events, and, significantly, that they produce distinctive interpretive experiences for readers and audiences alike. Iverson marshals an array of methodological perspectives demonstrating how performance generates a unique experiential context that shapes and informs the interpretive process. Iverson's study explores the dynamic oral environment in which ancient audiences experienced the gospel stories. He shows why an understanding of oral performance has important implications for the study of the NT, as well as for several
