Artist Julie Brook journeys to the wildest and most remote landscapes on earth, creating work that is not only inspired by the land but cut from it. For the Firestacks, her most recent series, created in the Hebrides, Brook assembles natural elements—water, stone and fire—to create a tidal work that expresses the vital tension between gravity and time, through the seasons. Robert Macfarlane’s engagement with wilderness is similarly immersive, conjuring landscapes, seas and underground spaces with a poet’s eye and a scholar’s tongue. As Brook debuts her new work, she discusses with Macfarlane the elemental forces at play in her work .
