Anthony McCall is a British artist who has long been active on the New York scene. He is known for having found a way to give shape to light through installations that use the projection of two-dimensional light beams in an impalpable fog. A technique that gives the illusion of creating “solid” light forms that occupy a space that thus becomes poetically “tangible” and “malleable”. Light immersed in the darkness of a non-place, suspended in time, immersed in a veil of a light and mist that stands out on a black horizon, invisible to the eye. McCall with his light sculptures very quickly achieved success that led him to be celebrated in important exhibitions around the world in the 1970s. A practice resumed after a twenty-year interruption in the 2000s when, despite changing projection technologies, McCall found a way to reinvent his solid light installations. The exhibition at Tate Modern presents photographs and films of the artist's early performances, including the significant Landscape for Fire from 1972, or some of his most significant works - such as Room with Altered Window from 1973 - demonstrating the artist's growing interest in light and architectural interventions.
