What is your favorite book on mixing?

[The Tone Ranger]

I'm trying to improve my mixing skills and I'm looking for all opinions/suggestions on books that you have read that you feel have greatly increased your knowledge about mixing and mixing skills. Thank you.

Paul White - Basic Mixing Techniques. Very useful (depending on your experience level)

I wish there was an engineering book catered towards hiphop/rap production. Mixing a rock album and a rap album seem like they would be done differently ,and usually those books have a lot more tips from rock engineers than rap.
