The experience changed his life. While spending thousands of hours with the cubs, Kilham discovered unknown facets of bear behavior that have radically revised our understanding of animal behavior. Now widely recognized for his contributions to wildlife science, Kilham reveals that bears are altruistic and cooperate with unrelated, even unknown individuals, while our closer relatives, the supposedly more highly evolved chimps, cooperate only within troops of recognizable members. Beyond the natural history, he introduces individual bears who become enthralling and memorable characters.

    Sound art’s roots can be found in the experimental work of Italian Futurism, Dada, and later the Fluxus group and the pioneering efforts of the American composer and artist John Cage. In the wake of this groundbreaking work, sound art began to mature into a movement, and artists explored the interactive possibilities of sound and in turn created entirely new modes of experiencing and engaging with art. In this volume, the complete story of sound art is told by one of the country’s leading critics and scholars. The author traces the history of this form of art–highlighting the convergence of the indie world bands such as Sonic Youth with the art world–looking at the critical cross-pollination that has led to some of the most important and challenging art being produced today, including work by Christian Marclay, LaMonte Young, Janet Cardiff, Rodney Graham, and Laurie Anderson, among many others.
