As many people in the general populus consider Heavy Metal as more entertainment than art, this book tends to bring to light more of the social & artful aspects of the music. As the title suggests, there's much to do with sociological issues of power, gender, and emotional views. But there was also a large undercurrent of the musical talent and influences of those who make H.M. music. Moreover, the view that H.M. is/not dominantly popular due to lyrical content alone was another interesting topic discussed (among other topics). It is true that some of the topics lack the proper explaination they ought, but for the most part, the details given are good & helpful. If you are a musician, this is a MUST HAVE book! For those trying to understand H.M. (parents, teachers, etc) - open your mind and open this book. Includes indepth looks at musical styles of: Eddie Van Halen, Randy Rhodes, and others.
