Second Life – 100 Arbeiter

On Air showcases a distinctive art form, the sound sculpture, retracing its evolution from the early 1950s, when artists begin dismantling the conventional boundaries of art, to the early 1970s. In no more than a quarter-century, the range of possible answers to the question “What is art?” grows vastly larger. Propelled by the idea of the work of art as a machine and instrument, sounds, noises, tones, vibrations, silence, words, breath become a “tangible” sculptural material. Artists enrich visual perception by adding the acoustic dimension, interweave seeing and hearing, explore time and space with fresh zeal. In emerging artistic genres such as performance, installation, or media art, sound is an integral component of the work. The book focuses on sound objects by Yaakov Agam, Joseph Beuys, Hermann Goepfert, Yves Klein, Jannis Kounellis, Bruce Nauman, Robert Rauschenberg, Jean Tinguely, David Tudor, Timm Ulrichs, and others.

With five scholarly essays and numerous illustrations and notes on individual works, the comprehensive publication offers an attractive introduction to the subject.

The interweaving of traces, sounds, and movements in an impressive work of sound art

The narrow brown magnetic tape of an audio cassette runs through a half-opened hand, slides through the fingers, is palpated in constant motion, and finally falls to the ground. The hand and its touching, particles of sand and small stones leave their traces and, when the tape is played, generate a multi-layered soundscape with crackling and background noises.
In her performative action in the ruins of the city of Messene in the Peloponnese region of Greece, Franziska Windisch (b. 1983) thematizes aspects of repetition and recording. Her artistic examination of the vestiges of the ancient urban space, the reciprocal transition from traces to writing in her video documentation, and the graphic element of the line visible on the ground lead to a reflection on temporality, dissolution, and decay.
