Here I explore three varieties of theatrical responses to the cultural amnesia brought about by what scholars have termed “post-AIDS” rhetoric. Specifically, I examine how AIDS history plays, AIDS comedies, and solo plays provide opportunities for theatregoers to participate in, or reflect on the absence of, what I call “AIDS mourning publics.” I understand these publics to be both the groupings of people that gather around a text, film screening, play performance, or event that was created in response to loss due to AIDS, and the text, screenplay, or play text itself when circulated. In these publics participants work through their grief, make political interventions, and negotiate the meanings of AIDS history for gay men whose sexual awakening occurred before and after the development of protease inhibitors. I join theories of grieving, affect in performance, and the public sphere to study these communal events. I use films, plays, and critical reviews to identify how mourning through performance can be therapeutic for cultural and social actors despite activists' and scholars' sole attention to the counterpublicity of these events. Still, counterpublicity remains an important concern because many in the dominant US public sphere consider AIDS to be a benign “manageable condition” in affluent countries like the US. As such, I also present a dramaturgy of mourning and counterpublicity in twenty-first century US AIDS drama and solo performance with attention focused upon how dramatists and solo performers are inviting spectators to engage with, and find new meaning within, this epidemic. For example, I investigate how pairing mourning with genres like comedy produces political interventions within the space between laughing and astonishment. My dramaturgy of mourning also examines recurring themes such as ghosts, the past, intergenerationalism, and AIDS amnesia to interpret how performers have framed individual and collective loss to challenge spectators' understanding of AIDS history. To support my claims I use sources from the New York Public Library Manuscripts and Archives Division, gay and lesbian community newspapers, personal interviews, and my own experiences as a spectator viewing productions of The Normal Heart, thirtynothing, and The VOID.
