** 2026 Stock. Leporello French/English ** Call to a Crow – Appelle un corbeau gathers a series of short poems by David Horvitz, originally conceived for the first Son Biennale in 2023, into a leporello that reads like a pocket field guide to listening and imagining in the Alps. Each phrase is both poem and instruction, a small performative score that invites the reader to tune themselves to the landscape and its absences. “Imagine the sound of the footsteps of someone who is no more,” “Imagine the silence emanating from a vanished glacier,” “Call a raven until a raven calls you back”: these lines open up spaces where memory, ecology and grief mingle, linking the physical environment to the invisible presences that haunt it. Printed in English and French and choreographed across the folded pages by graphic designer Romain Iannone, the texts unfold in space as much as on paper, echoing their call to step outside oneself and listen.

Before becoming a book, the project already had a public life. The poems were dispersed across Valais on the regional poster network, appeared on a large billboard in the town centre – on a site regularly activated by EDHEA (École de design et haute école d’art du Valais) for graphic and artistic interventions – and surfaced in the local press. In each context, they worked as gentle interruptions of daily perception, dropping a line of speculative attention into routines of commuting, shopping or reading the news. The leporello consolidates that dispersed presence, offering a portable version of the same invitations: to imagine sounds that no longer exist, to register the silence left by retreating ice, to enter into a call‑and‑response with non‑human life.

Born in 1982 and based in Los Angeles, Horvitz studied at the University of California and Waseda University in Tokyo before completing an MFA at Bard College in 2010. Influenced by artists like Bas Jan Ader and On Kawara, he has built a body of work that plays with time, language and exchange across media – writing, photography, performance, postal projects, online interventions and subtle actions in public space. He has described the ocean as his “workshop,” transcribing its sounds into alphabetic posters and flags in When the ocean sounds(2020), mailing plant cuttings from his Californian garden to Berlin during lockdown, and bottling Los Angeles air in glass vials in a wry homage to Marcel Duchamp that also evokes viral breath and wildfire smoke. Recipient of the Follow Fluxus – After Fluxus grant in Wiesbaden (2020), Horvitz is celebrated for using simple, everyday means to stage complex reflections.
