A central figure in the California Light and Space movement, Laddie John Dill has been crafting light and earthy materials like concrete, glass, sand, and metal into luminous sculptures, wall pieces, and installations since the 1970s. Referring to his choice of materials, Dill explains: “I was influenced by [Robert] Rauschenberg, Keith Sonnier, Robert Smithson, Dennis Oppenheim, and Robert Irwin, who were working with earth materials, light, and space as an alternative to easel painting.” Among his most celebrated works is an untitled installation from 1971, for which Dill filled a gallery with mounds of pale sand, topped with precisely arranged glass panels illuminated by the soft, green glow of argon lighting set just beneath the surface. When he does use canvas, he paints with pigments derived from cement and natural oxides.
