Witness

Susan Hiller (March 7, 1940 – January 28, 2019) was a US-born, British conceptual artist who lived in London, United Kingdom. Her practice spanned a broad range of media including installation, video, photography, painting, sculpture, performance, artist's books and writing. A key figure in British art across four decades, she was best known for her innovative large-scale multimedia installations, and for works that took as their subject matter aspects of culture that were overlooked, marginalised, or disregarded, including paranormal beliefs – an approach which she referred to as "paraconceptualism". -Wikipedia
