Query: could have been better

I think the authors intentions were good but this book left much to be desired. The audio clips were somewhat helpful but most of clips were of the same song/vocalist over and over again. Showing contrast as changes were made to the vocal track, but really only scratching the surface of what can be a very important and multilayered process. His examples are clear but it would really be great if he could follow up this book with another with 4 times more info. I would pay more $ for a better book from this guy because I think he really does know what he is talking about. But this book was disappointing. Sorry :<
