Mariana Pellejero (Buenos Aires, 1974) is an Argentine visual and sound artist currently living and working in Mar del Plata. Her work explores the connections between matter, copy, and sound, traversing the boundaries between the natural and the artificial. From May to October 19, she is exhibiting GEMELITA at the Museum of Contemporary Art of Buenos Aires, where she brings together a series of previously unpublished works that deepen her exploration of the technical and conceptual possibilities of copy.

The artist creates a space for artistic experimentation where various techniques converge. These include embossing, which consists of creating reliefs on surfaces such as paper, fabric, or metal to give them a three-dimensional and textured effect; frottage, which involves rubbing a pencil over a sheet of paper placed on an object to capture its texture and shape; along with photographic techniques and the artisanal production of oil pastels. This workshop aims to explore the expressive possibilities of matter, recording, and imprint as visual languages.
Pellejero develops his work using a wide variety of materials and techniques—engraving, embossing, frottage, photography, oil pastels, and installations—that connect manual gestures with sensory perception. In his most recent work, such as the exhibition "Gemelita" presented at the MAR Museum, he explores the technical and conceptual dimensions of copying, duplication, and the transformation of matter, using ancient geological formations such as the Tandilia system in the province of Buenos Aires as references.
In parallel, her sound practice unfolds through the use of analog instruments and everyday objects, in an exploration close to improvisation and acoustic experimentation. Both visually and sonically, her work invites an experience in which texture, relief, and sound intertwine, generating a space for contemplation and material resonance.

For his exhibition, he worked with stones from the Tandilia system, the ancient mountain range that runs through the center of the province of Buenos Aires and extends to the Atlantic coast. Through a series of duplicates, stereographs, and stone stelae, the exhibition explores the processes of replication and transformation of matter, highlighting the increasingly porous boundaries between the natural and the artificial.
Mariana Pellejero thus constructs her own universe in which the copy, the trace, and the echo—visual or sound—become tools for considering the persistence of time and the memory of materials.
