My central research focus seeks to define a poetics of the carceral; to accomplish this goal, I study the relationship between inmate authors, the space of the prison, and the soundscapes their works create. My work builds on that of scholars like Nicole Fleetwood who have shifted conversations toward the materiality of the prison in recent years. My work emerges in conversation with this scholar, as I expand her frameworks to examine how the material shape of the prison is revealed through and imprinted on the work of incarcerated poets. In my paper, I argue that inmate authors articulate the prison experience in unique ways by reconstructing and experimenting with sound to push back against a dehumanizing carceral space. I begin by foregrounding the work of Reginald Dwayne Betts, as he uses the material prison to create soundscapes of his experience. His material use of legal documents and prison moderators creates a tension between the sounds the prison implicitly creates, and those Betts explicitly recreates. The sensory experience of prison, how it is heard and seen, and the recreations of that experience allow us to understand the architecture of carceral space. Ultimately, my paper identifies new directions for analyzing how inmate artists transform the experience of carceral space and inscribe the material life of the contemporary American prison into poetry.
