“Sons do Subterrâneo” (Sounds of the Underground) is an editorial project that, through interviews and photographic essays, follows the performances of six street artists who perform in the subway stations of São Paulo. In São Paulo, performing music or other artistic expressions in subway premises is prohibited. To avoid security guards, the artists began performing inside subway trains, moving continuously between stations and switching lines. The editorial project is composed of two pieces: a larger block containing the interviews, which embraces a smaller photographic essay in its center, featuring images of the subway environment. The grid plays with the rhythm between the text blocks and the images of the artists, which are sometimes placed at the edges of pages and continue onto the following spread, creating a sense of movement. Page elements, such as interview numbers and page numbers, are inspired by the typographically dense, signage-oriented environment of the subway. The metallic silver color, sets the visual tone of the book, evoking a mechanical, urban reality. In the photographic section, this metallic tone is embedded into the images, highlighting metal details through silver pigment.
