For over twenty years, São Paulo-based artist Rivane Neuenschwander has honed a distinct multimedia practice that investigates the roles of collaboration and chance in the creative act. Whether in film, photography, or installation, Neuenschwander is principally concerned with what she calls “ethereal materialism,” or the role that ephemeral or everyday materials have in creating momentary experiences of wonder, chance, and enchantment in public space. The installation Um festival embananado is the sixth installment of a series of works Neuenschwander began making in 2004 titled Zé Carioca. The series title is a reference to the comic character José “Zé” Carioca, a dapper Brazilian parrot first created in 1941 by cartoonist José Carlos de Brito. The next year, the character was famously adapted by the Walt Disney Company as a companion of Donald Duck and later of Mickey Mouse. The creation of Disney’s new character was an extension of Franklin D. Roosevelt’s Good Neighbor Policy, which sought to maintain strategic relations in the Americas—in this case through popular culture. Frequently featured in comic strips, animated films, and television shows, Zé Carioca has become synonymous with Brazilian culture even as the character’s stereotypical traits as a suave, streetwise malandro (rascal) speak to the complicated history of American political interference in Latin America in the twentieth century. In her series, Neuenschwander creates mural blocks of Zé Carioca’s comic panels stripped of the original text and image, leaving only vibrant, Technicolor squares and blank speech bubbles. The artist then invites the public to continue the artwork by writing or drawing directly on the murals. The result is a collective form of social and individual expression determined entirely by the chance encounter in public space.
