This book is a distillation of interviews by the author with numerous influential experts in the field of studio mixing. The interviews themselves are included for completeness. It starts off well, suggesting it is going to be an in-depth, topic-by-topic consideration of all you need to know. Indeed the book's structure suggests that's how it will pan out. Sadly, it does not maintain this style and becomes increasingly inconsistent as you progress. A prime example of this, and there are several others, is the section on compression, where the author begins by explaining that compression is used to control dynamics and thus make the sound more even - so basic stuff - then launches straight into technical suggestions of specific ratio settings without any explanation of what might be a ratio, a threshold, knee settings and all the gubbins that make compression so complex an issue. Basic, then suddenly technical, like somebody ripped out a few pages in between - or perhaps that the author did not have a clear idea of his book's mission.
This pattern of inconsistency turns the book from a promise of instruction into essentially an anecdotal indulgence. It's worth reading, but only out of specialist interest and only if you already have at least a grounding in mixing technologies.
A further warning - the unflinching bias toward studio-based hardware solutions (a declining sector, as the author himself notes) makes this book of limited use to composers and producers who do everything in a software-based Digital Audio Workstation like Cubase, Sonar or Reason etc.
