The Chelsea branch of Dia Art Foundation reopens with newly commissioned works by American artist Lucy Raven. Two kinetic light sculptures, Casters X-2 and X-3 (2021), surveil the gallery with moving beams, while the immersive film installation Ready Mix (2021, image) documents the workings of an Idaho concrete plant. Capturing the churn of mineral aggregates and cement binders with optical and durational experiments, the 45-minute film expands on Raven’s preoccupation with resource extraction in the American West.
