This is such an interesting topic. Any general mixing should not be done until you have recorded all the tracks. These days, many Producer's and ME's make this one big mistake: They get into the habit of recording music in terms of what they think they can *fix* later on. It's a hard road to hell, but it would be best to learn to record things the way you like them first, knowing you aught to save any general post process until you have finished everything. Doing so would actually gain you a couple things: 1. Insite on how well you recorded the tracks, and 2. Intuitive ears on what is needed/wanted in the mix, both broad and specific.
A good analogy for this growing production industry anomaly is Auto-Tune: Everyone tends to *care less* on the tracking quality of vocal precision because they've got Auto-Tune or Melodyne.
Another great analogy: Vocalign! We don't need to worry too much about our guitar double-quadrouble-octopus rythm tracking, do we?! NO. We've got Vocalign
^^I'm expressing the issue of what producers can go through across the board with their mixing adventures (particularly beginner's and amateurs). It's a bit like EQ--producer's will start tracking songs and, under their subconscience, know they will fix it later. OUCH. They don't even know that's happening...
In regard to everything I've stated, there are still instances where you want yourself and the band to be comfortable with what they're listening to--the monitoring environment. Especially, If you don't have any, or have minimal rack equipment being used, you will most likely need/want some processing (compression to hear the vocals while tracking, kick needs EQ help so the bassist can stay on track with rythm of the drums/percussion).
REMEMBER: The better you become at tracking with a natural, unbiased perspective, the more insite and wisdom you will have when, after tracking, sit back, listen you what you've got, hearing things outside the box.
As human beings, we are very adaptive creatures. What this means (and you will probably shake your head and say, "No, not me!") is that if you are mixing things very prematurely, you will become adaptive to it, and at some point, way down the road, you will be hearing things wrong in your mix, and you won't know where it started to go wonky. That's because you're too dang excited to mix! Be excited to track FIRST, then get excited about mixing what you've done. Every project you handle like this will bring you closer and closer to Mix GURU.
