First off, the title of this book is a little (okay, a lot) misleading. From the title, you would think it would be a light-hearted, casual intro to dance music. This is not the case. This book is like a massive compendium of every single concept you would ever want to know about dance music, or anything like unto it. The first pages are all about sculpting sounds from waveforms, and it's not easy reading! As a matter of fact, that's my only criticism of this book - so much of it was over my head. But what the author lacks in his ability to explain concepts to complete newbie/morons (like me), he more than makes up for with his vast amount of knowledge, and the breadth of the subjects in the book. This really is EVERYTHING you could ever want to know about dance music - how audio works, how synth programming works, dance music trends, effects, etc.
And the author doesn't just tell you the "how", he tells you the "why". It's a book for both artists and techies alike, which is a hard line to straddle. I really have enjoyed this book, and will no doubt read it again as soon as I'm done. It's opened my eyes to soooooo much!!
