this one and mixing audio are my 2 fav mixing books. both are well worth whatever they cost.
off the top of my head...liked all the talk about comb filtering (it's not just monitoring yo), time and pitch correction, the often uselessness of grids for time correcting live performances, the various effects of reverbs, monitoring on a budget. there is a lot of good stuff i didn't know in there.
i do wish he described compression a bit different. it's a bit more then quick volume changes. i wish he got to automation earlier. i think it deserves a higher rank.
i've yet to build a mix per the book. but probably will soon.
