Artist LaRissa Rogers invites you to learn about the historic material of tabby and to cast objects to be included in her forthcoming installation, subterranean convergence (opens Fall 2026). Tabby is an ancient building material from North Africa, used by enslaved peoples in the American South. This workshop emphasizes material history, storytelling, and the ways survival technologies can become tools for remembrance.

subterranean convergence, a sculptural installation and performance score by LaRissa Rogers at Los Angeles State Historic Park (the former site of the Southern Pacific River Station) that draws on the geographies of the transcontinental railroad between the American South and West to investigate the ways Black and marginalized communities have conceptualized liberation—and where it might still be. Within simulated railroad tracks, Rogers will install tabby-casted objects sourced from institutional archives and invited community members. 

RSVP link coming soon.
