I love this book very much. I love the cover, particularly the horizontal format back cover,the clear methodical concise but never sterile six part- 18 chapter format with which it is divided. Hell i even love that the publisher is called continuum. It is a revelatory experience to read this tome. You may be an experienced connoisseur, practitioner,curator, student or complete sound art virgin LaBelle will lead you through the soundscape, listening anew to works of great simplicity or complexity with the same deft insights. It is no easy task to write about and describe sound and LaBelle's genius is in making it seem easy by employing perspective. It is not called "Perspectives on Sound Art" for nothing. Sound without a contextual space in which to express itself is like paint bereft of canvas on which to be fixed. It is the reflections on sound art alumni from Schaffer through Cage and Lucier to Fontana that echo in your head long after putting the book down. He talks about the development of sound art through not just the artists and works produced, but by dissecting these in logically grouped contexts of how they inter-relate. The clever grouping of sub-genres or classes of sound art really help in navigating a clear developmental line through the "Background Noise" and the introductions to each part along with the clearly delineated cross referenced notes at the end of each chapter make this an invaluable guide for students and teachers alike.The black and white Photographs / illustrations are both informative and beautiful and really add to the books usefulness. I cannot recommend it enough, if you are interested in Sonic Art this book will engage,inform and enthuse you and its authors spatial thinking will also help you understand how many other forms of contemporary art from installation to performance have been influenced by the men and women who have made the interpretation and application of sound their lives work.
