Query: Very Disappointed

The book is a random core-dump of Bob Katz's audio engineering knowledge, but it is completely lacking any organization that would facilitate an effective learning process for the reader. Two major aspects of the book are very poor. First, it is completely lacking a quality introduction and chapter sequencing that would promote knowledge transfer. Second,it is very deep in technical jargon and very thin on learning points. I have read a lot of material in pursuit of developing a better understanding of mixing and mastering, this would rank near the bottom from a learning perspective. I will give it one high mark...it is "glitzy" and professional looking.
