articles, articles, articles. Good for quite a few things (I'm a total geek and do read a lot of geeky articles that are rather useful), but I can't see that mixing would be one.
If you're mixing a style of music you've never mixed before - or mixing for the first time at all - just grab some records you really love the sound of and rock them in a good pair of headphones until you feel like you get it:
Listen for where things are placed in the stereo field, what frequencies certain instuments seem to be occupying, where the levels are and whether it sounds good or not so good that way, how effects are used and where they sit in the mix (and also to what instruments they are applied), etc. If you hear a texture or sound that is interesting, bend your brain towards figuring out how that sound or texture was achieved or, maybe more importantly, how you would have gone about conveying the same thing. Listen to records with 15-peice bands (The Boss) and listen to records with just a guitar/piano and a vocal (Cash, Leonard Cohen, etc) and pay attention to how the big stuff is kept sounding sonically clear and how the simple stuff is made interesting and intimate. Also, once you've gotten to really know those records inside and out in headphones, listen to them on every stereo within a ten mile radius and see what different characteristics those sounds take on when played through speakers of varying size, quality, and configuration.
Then spend 20 hours or more on a mix until you feel like you're starting to learn how to apply what you've learned by listening. At that point, articles might come in handy, but until then, I say just roll up yer sleeves, my man. The best mixes, in my opinion, don't (necessarly) come from people who've just been around a while and have really nice gear. The best mixes come from people who just have very well-tuned, unique, and intuitive ears (though and SSL doesn't hurt!). Best of luck, you'll have tons of fun!
