Form in the Age of Living Materials. Interview with Curator Pablo José Ramírez

LA FORMA EN LA ERA DE LOS MATERIALES VIVOS. ENTREVISTA AL CURADOR PABLO JOSÉ RAMÍREZ

The Hammer Museum in Los Angeles is presenting "Several Eternities in a Day: Form in the Age of Living Materials," an exhibition curated by Pablo José Ramírez running until August 23. Featuring 22 artists from the Americas, the show explores materials such as avocado, cacao, achiote, cochineal, stone, clay, and natural dyes that evolve, degrade, or transform over time. Organized into three acts, the exhibition challenges conventional notions of the art object by treating these materials as living agents with memory and agency, rooted in Indigenous knowledge and the concept of "brownness." In an interview, Ramírez discusses how these materials destabilize extractivist logics and institutional frameworks, forcing a rethinking of conservation protocols and the very conditions of exhibition-making.
