This book includes Brancusi, Richard Long, James Turrell and others. Updated and expanded, this fourth edition crosses boundaries of art and urban landscape planning. The book begins with an enlightening introduction tracing the historical roots of art in the landscape: Stonehenge, Indian mounds, cliff dwellings, park design from 18th-century England to modern-day golf courses. The opening chapter deals with such innovative artists as Robert Smithson, Nancy Holt, Walter De Maria, and Christo, who in the 1960s began to free their art from the confines of tradition by constructing monumental sculptures in the environment. The following chapters ! discuss their predecessors, peers, and successors, including Constantin Brancusi, Herbert Bayer, Richard Long, James Turrell, and many others. The final four chapters (chapter 7 is entirely new) explore at length the increasing involvement of artists in land reclamation and urban design, featuring projects by Michael Heizer, Nancy Holt, Mel Chin, Maya Lin, and many others.This book was converted from its physical edition to the digital format by a community of volunteers.

It utilizes a very small, very accurate omnidirectional element, a carefully crafted stainless steel body, and innovative circuitry to deliver flat, time c! oherent response from 9 Hz to 30 kHz. The M30 has become the d! efacto s tandard reference for Smaart, MLSSA, SIMM and TEF. The M30 is the most cost-effective measurement microphone which you can trust. It exceeds the specified requirements for al audio band measurement systems. The M30 is a standard.The M30 comes with a measured frequency response chart which includes a value for sensitivity. Since the M30 is stable with respect to temperature, you can input this number if your program allows and be very close to correct absolute SPL. We also ship the M30 with a 'white' calibrator adapter which adapts from the M30 to a 1/2-inch calibrator adapter for field calibration.The M30 is available as amatched pair and doubles as a great sounding recording microphone. It is sturdy and reliable. The M30 is a sound investment.
