This ground-breaking volume, beautiful companion book to the exhibition of the same name, is the first comprehensive study of Nancy Holt, the visionary American artist. Holt's wide-ranging body of work beginning in the late 1960s includes land art - particularly the monumental 'Sun Tunnels' (1973-1976) - major works of sculpture, installations, film, and video. Essays by a diverse and distinguished group of authors - including Lucy Lippard, Matthew Coolidge, and Pamela M. Lee - chart the artist's fascinating trajectory and take us from her initial experiments with sound, light, and industrial materials to the culmination of her development of major site interventions and freestanding environmental sculpture. This book shows that as Holt's interest in physical space matured, the geological variety and seeming boundlessness of the American landscape afforded her numerous opportunities to develop large-scale projects beyond the confines of New York City's gallery walls. Including James Meyer's valuable interview with Holt and rare, unpublished texts, photographs, and artworks, the volume expands our knowledge of this important artist and the crucial contexts in which she worked, along with her revolutionary concepts of space, time, optics, perspective, and more.
