This is the first retrospective study of Nancy Holt, the visionary American artistÂ—a landmark companion book to the Â“Nancy Holt: Sightlinesâ€ť exhibition. Holtâ€™s wide-ranging body of work since the late 1960s includes Land artÂ—particularly the monumental Sun Tunnels (1973-1976), major works of sculpture, installations, film, and video. A comprehensive representation of her working process in both word and image, this book illuminates Holtâ€™s interest in physical space and reveals how the geographic variety and boundlessness of the American landscape afforded the artist numerous opportunities to develop large-scale projects beyond the confines of New York Cityâ€™s gallery walls. Essays by a diverse and distinguished group of contributorsÂ—including Pamela M. Lee, Lucy R. Lippard, Ines Schaber, and Matthew CoolidgeÂ—chart Holtâ€™s fascinating trajectory from her initial experiments with sound, light, and industrial materials to major site interventions and environmental sculpture. James Meyerâ€™s valuable interview with Holt and Julia Aldersonâ€™s illustrated chronology expand our knowledge of this groundbreaking artist and the crucial contexts in which she worked. More than twenty original writings by the artist and a rare selection of her concrete poetry, documentary photographs, and preparatory drawings reveal Holtâ€™s revolutionary concepts of space, time, optics, and scale.
