Studio Recording Procedures: How to Record any Instrument by Mike Shea. Bought it a week ago, hard to put down, absolutely chock full of amazing things, from miniscule details to very large scale concepts. Heavy and satisfying read. mmm…mmm… 
So new it’s not even on McGraw Hill’s website (the publisher).
Oops, I was wrong, they have it under a different title:
http://books.mcgraw-hill.com/getbook.php?isbn=0071422722&template=
Weird. Well, I guess it’s called
Ultimate Guide to Music Recording now. 
Edit: oops again - they seem to be mixed up, the title is as I have it, the picture is as it is on the McG-Hill webpage, but what they have for contents is a different book. Anyway, go look at this one at your local Borders or whatever.
