Query: Academically sound but misses the point

Weinstein here executes an academically well-trained description of the heavy metal genre, but in doing so agglutinates several generations of metal into one pseudo-genre which, not surprisingly, does not fit the broader conclusions academics must draw from sociological studies. This book repeats the classic error of all academics in assuming all metal is Motley Crue or derivates thereof, and consequently, the book is completely obsolete in the current time. Well-written and smoothly flowing it is an afternoon's read and provides great supporting evidence for any mainstreaming or assimilation of the heavy metal lifestyle in academia.
