David Hammons' "Untitled (Rock Head)" sculptures are compelling pieces that utilize a combination of natural materials and human-made elements to explore themes of identity, culture, and the African-American experience. Created in the mid-2000s, these sculptures are composed of stones adorned with hair, presenting an unconventional form of portraiture. By affixing afro-textured hair, which he sourced from African American barbershops, to the rocks, Hammons crafts portraits that are deeply evocative of Black identity, while also engaging with a broader dialogue on human presence and representation.

The "Rock Head" pieces extend from Hammons' practice of employing found materials and making references to the body to create works that evoke visual tropes of Black identity. This method is rooted in his earlier performances in Harlem, where he gave haircuts to similar objects, employing human hair in a manner that is both literal and symbolic. These works underscore Hammons' interest in utilizing recovered materials and body references to challenge and interrogate societal perceptions and stereotypes​ (RISD Museum)​​ (www.wikiart.org)​​ (RISD Museum)​.

One particular "Rock Head" sculpture, documented in the RISD Museum's collection from the year 2000, is described as a stone and hair piece mounted on a metal stand. This sculpture, and others like it, is significant not only for its materials and technique but also for its placement within the context of contemporary art. By presenting "Rock Head" alongside historical and contemporary portraits, the works encourage viewers to draw comparisons and consider the timeless simplicity and profound depth of these sculptures, despite their humble materials. This approach reflects Hammons' broader practice of juxtaposing his work within diverse artistic traditions to highlight enduring themes of racial perseverance and identity​ (RISD Museum)​.

Hammons' "Rock Head" sculptures are a testament to his innovative approach to art-making and his deep engagement with themes of racial identity and the complexity of the African-American experience. Through these works, Hammons invites viewers into a dialogue about the nature of representation and the power of simple, everyday materials to convey profound cultural and historical narratives.
