just ONE book

Michael "Stav" Pavrou has changed my life and perspective with respect to all things mixing, music, and recording. His techniques challenge 'science' and 'common sense' approaches taught in "recording schools." This is the kind of book that isn't meant to be read in a sitting, or over time, but rather carried as a reference and used before any project that one is about to take on. He really does cover it all... 

As you'll start to understand, I don't like to hype up things or talk bad about them. When I share something, it has already made it through my filter and is something I believe anyone else would benefit from. Of course, to get to books like this, I had to sift through many, many, of them. However, books like this come across my radar in some magical kind of way, and this one was no different. Enjoy
