Reply to Essential Reading For Digital Producers?

Hey guys , post your Essential Reading (or viewing if you have good videos) for more advanced aspects of digital producing (no beginner guides please).
Recommend your favourite Blogs, Forums/Threads, Manuals/Tutorials, E-Books. I'm most interested on brushing up on proper mixing techniques with the use of a variety of signal processing plug-ins. The only reading I have on the subject is quite dated so newer info that features newer techniques like Parallel Compression or older techniques using newer software etc. are things I'm interested in.
thanks!
