Yanko González (Santiago de Chile, 1971) is a sharp and merciless observer, and perhaps that is the main reason the boundary between art and science, or more specifically between poetry and anthropology, sometimes appears very porous in his poems. Metales Pesados (1998) is an experimental, poetic elaboration of his ethnographic research about marginalized youth groups; it offers reflections on slang, critical theory and anthropological practices. In other collections, González surprises the reader with his well thought-out approaches, and he demonstrates a commitment to themes such as class struggle, relationships, discourse and distinctive uses of language in a thorough, original way.
