British artist Anthony McCall (born 1946) has a cross-disciplinary practice in which film, sculpture, installation, drawing and performance overlap. McCall was a key figure in the avant-garde London Film-makers Co-operative in the 1970s and his earliest films are documents of outdoor performances that were notable for their minimal use of the elements, most notably fire. After moving to New York in 1973, McCall continued his fire performances and developed his ‘solid light’ film series, conceiving the now-legendary Line Describing a Cone (watch a video of a gallery-goer’s interaction with it), in 1973. These works are simple projections that strikingly emphasise the sculptural qualities of a beam of light.
