Their have been more useless books written on the subject than could be imagined, this book is different. The author presents things in practical, everyday working man's terms so that you can develop your craft. No endless theories, or stylistic axes to grind. The fact that this book went out of print while volumes of trash get reprinted every year via academia is nothing less than a tragedy. This book is about presenting possibilities but not necessarily explaining them, so you gotta have a handle on things.
