[Text available only in English] An urban symphony of Mexico City. The large megalopolis portrayed in detailed textures, patterns and rhythms of massive fluids. Full of contrasts, one of the most populated areas of the world, with that unique flavor of the great urban heart of Mexico. Sound production is performed live by members of the Post Kaput collective who use electroacoustic instruments built with recycled materials and electronically processed to create environments and sound objects with massive doses of noise.
