Anthony McCall's seventh solo exhibition with Sean Kelly brings three generations of his "solid light" installations together in one show, spanning more than five decades of a practice that treats projected light as a sculptural medium. The exhibition centers on *Line Describing a Cone* (1973), the landmark work in which a beam of light from a film projector draws a slowly evolving cone through haze-filled space, inviting viewers to move around and through the volume. It is shown alongside *Skylight* (2020), a later example of McCall's digitally driven light works, and *Swarm* (2026), a new piece receiving its debut in the show. McCall first developed the solid-light films in 1970s New York, where his performances attracted figures from the downtown art and music scenes. His return to international prominence came in the 2000s, and the installations have since been embraced as some of the most influential works of expanded cinema, bridging minimalism, performance, and immersive art. On view from 11 September to 31 October, the exhibition arrives at a moment when immersive light-based art dominates the cultural conversation, offering a chance to see the originator's precisely calibrated works rather than the crowd-pleasing digital spectacles they inspired. The gallery presentation in New York underscores McCall's long standing with Sean Kelly, which has represented him through the most productive phase of his second act.
