Curated by Campos de Marte + Performance by Marco Padiya With contributions from Marta Echaves (Caja Negra) and Natalia Piñuel The focus on listening, a feature of the 2025 edition of Un cuarto de estar para la ciudad, is interwoven this year with a reflection on communities — the central theme of this new edition — giving rise to a session conceived around the overarching idea of a ‘listening community’. Building on this notion, the proposal is for a sensitive, shared space for encounter, where listening is no longer understood as an individual experience but becomes a collective practice, capable of forging bonds, fostering affection and shaping ways of inhabiting the shared space. Re-sisters, Thursday 23 July at 7.00 pm, Marta Echaves (Caja Negra) and Natalia Piñuel In collaboration with the publisher Caja Negra, this event offers a conversation and listening session centred on the original soundtrack composed by the artist Cossey Fanni Tutti for the 2020 documentary on Delia Derbyshire, a mathematician and key figure in 20th-century sound experimentation. Delia Derbyshire’s practice and research form the starting point for Cossey Fanni Tutti’s *Re-Sisters* (2022), a book published in July by Caja Negra, which traces the female lineages of experimental music and invites reflection on listening, mysticism, collective creation and forms of cultural resistance. The session will revolve around these two points of reference, encouraging participants to listen to tracks and compositions by Delia and Cosey, alongside other more contemporary music, and to take part in a shared reading of excerpts from the book. It will also explore the concept of personal music archives or sentimental biographies, alongside the idea of heritage or legacy.
