One of the lines of work undertaken by CA2M is to revitalise the history of contemporary art exhibitions in Madrid. For this one-object exhibition by Nacho Criado, we focus on Madrid: Espacio de interferencias (Madrid: Space of Interferences), curated in 1990 by the art theorist and historian Javier Maderuelo (Madrid, 1950) for the Círculo de Bellas Artes.
