Drawing on fifteen months of fieldwork in Brazil, this paper examines bailes de corredor (corridor events) hosted in the 2020s, focusing on sound and attendee sensorial structuring; sound and masculinity; and the effects of sounds associated with criminal governance on attendee behavior. Organized since the 1990s, corridor events feature fighting between two opposing sides separated by a space called the “corridor.” Each side is comprised of galeras (crews), groups of dozens of people who represent neighborhoods and, in perpetuity, Lado A (A-side) or Lado B (B-side). After the state criminalized events in 2000, organizers moved them to areas under criminal governance. During contemporary events, criminal groups often order the shutting off of music and, also, fire gunshots in attempts to control attendee behavior in a setting of overlapping sovereignty with the state—a setting in which criminal groups hold disciplining power but fail to command absolute authority. This lack of absolute authority shapes attendee responses to gunshot sounds and structures attendee sensorial capabilities while supporting attendee opposition to criminal groups. Engaging scholarship on sound and criminal governance (Cavalcanti 2008; Gilsing 2020; Lippman 2021), this paper shows how participation in contemporary corridor events shapes attendee sensorial capabilities in settings of overlapping sovereignty in areaas under criminal governance, framing attendee interactions with criminal groups.
