In this special issue, we 1 build on Bauman's seminal observation about performance, that 'the act of expression is put on display, objectified, marked out to a degree from its discursive surrounding and opened up to interpretive scrutiny and evaluation by an audience ' (2000:1). More recently, scholars have moved to examining the performative role of heteroglossia, that is, the use of multiply sourced, semiotic (verbal and nonverbal) forms. 2 In particular, this line of research has shown how attention to heteroglossic performances and their local interpretations can illuminate the subtle politics of dominant and nondominant identities in different ethnographic contexts. This is particularly true of what Coupland (2007) calls 'high performances', which, as Bell & Gibson (2011:558) write, are privileged sites for allowing participants to indexically associate expressive forms with social personae. Thus, while all performances are inherently reflexive, heteroglossic performances particularly amplify that reflexivity with respect to their multiple frames, voices, and stances that they presuppose and establish.The articles in this special issue thus investigate the diversity of heteroglossic resources, associated processes of social identification, participation frameworks, and political implications at stake in performance. The articles examine how performers evoke, stage and implicitly evaluate recognizable voices from the larger social world, and how audiences respond to and display their recognition of performers' aesthetically and politically charged stagings of those voices. As a collection, the articles then also explore how people use sets of semiotic resources to gradiently challenge and/or reinscribe normative ideologies and locally recognized, hierarchically organized identity categories.
