The book is filled with commentaries on the groups and songs, psychedelic drugs, album and single chart statistics, the music festivals and numerous opinionated lists. There are also unusual trivia and lyric identification questions.
The book is different from any other music book.
It is written for non-musicians (which are the vast majority of music listeners) and gives a very different perspective than most other music books.
Secondly, there is some biting humor in it, as the author pokes fun of musicians and some of the events of the time, which most music books tend to revere.
If you enjoyed the music of that era, or want to learn more about it, this book should interest you.
