Curated by Arnau Horta, and following the link between the sound arts and intangible heritage, the program of sound interventions "Sons de la Memòria" at El Born Centre de Cultura i Memòria of Barcelona is intended as a framework for the presentation of live performances, sound installations and other hybrid formats that explore the issue of memory and its malleable nature through music. Sounds (and music in particular) have a unique ability to trigger emotional reactions and relive lived, perhaps forgotten, stories, inviting us to reimagine and even fictionalize memory. Under the effects of music, memory can become an evanescent and ghostly material, pierced by imagination and fantasy. It is in this sense that one must understand the notion of "hauntology" that cultural critic Mark Fisher (1968-2017) borrowed from Jacques Derrida to describe a series of musical proposals that seem to oscillate between nostalgia and aspiration for a lost future, projecting itself back and forth in time.
