In October 2018, Transitional Object (PsychoBarn) by Cornelia Parker (born 1956) was recreated in the courtyard at the Royal Academy of Arts, London. This meticulous and unsettling installation--first shown on the roof of the Metropolitan Museum of Art, New York, against the skyline of Central Park--is half stage set, half sculpture. The work, which draws on archetypal images of American culture such as the red barn and the infamous Bates house from Alfred Hitchcock's Psycho, will now be seen against a backdrop of Burlington House's neoclassical buildings. Parker is internationally admired for her installations, including Cold Dark Matter: An Exploded View (1991), a reconstruction of an exploded shed. Generously illustrated with supporting imagery and installation shots, this book comprises a conversation with the artist and a text on the work's installation in London.
