Disclaimer: I have been a huge Rush fan for most of my life. I own all their albums (many in multiple formats) and videos, and have seen them live in concert on numerous occasions dating back to the 1980s. Alex Lifeson is the reason I learned to play guitar 30 years ago. Needless to say, my interest in and enjoyment of this book come with significant bias.
Although the book reveals little new information about Rush's music, it eloquently presents the band's career within a larger social context and offers fresh insights. As the title promises, this is a study of the relationship between rock music (specifically Rush, but including other relevant bands as well) and the middle class (specifically white, male, North American).
The author, who has a Ph.D. in ethnomusicology and is a university professor, exhibits considerable musical knowledge and facility of language in conveying such knowledge. He is able to intelligently discuss not only the lyrical content of songs but also their instrumental composition, e.g., use of time signatures, modes, quartal harmony, etc. This makes for a denser but more well-rounded read than is typically found in books about rock music, which often focus exclusively or predominantly on words.
Many Rush fans, myself included, have long felt a personal connection to the band. We discovered them at a particular time in life while searching for identity and meaning, and found that they spoke to us in a way that few other bands did. While this may have made each of us feel special on an individual basis, it's more than a little amusing to realize that so many shared the same "unique" experience.
What I learned more than anything from this book is that given my gender, cultural background, and socioeconomic status, my discovering and falling in love with Rush was not only predictable but also possibly inevitable. So much for freewill. (Sorry, couldn't resist a little Rush geek humor.)
The other thing I learned, which is arguably even more important, is that as a member of said gender, background, and status, I take certain things for granted as universal that are not in fact universal but are rather only agreed upon by a certain subset of the population. Being able to see outside one's own sphere is difficult if not impossible, but at least being aware that one is in a sphere alongside many others is a step in the right direction, especially in the current climate.
Overall, this book was well conceived, well researched, and well presented. It gave me much to think about, and I'm sure I'll read it again at some point to pick up any stray bits I may have missed the first time.
