Here, he advocates setting up two submix tracks - one for drums and bass and the other for 'Everything Else' and then mixing each individually, then blending the two. I thought this made sense as drums and bass are the foundation of most songs. Of course this has to be genre specific and dependent on your normal workflow; but I discovered a slight variation which works really well for me and my type of music.
I generally balance things as I progress in the production, but when it comes to the final mix, I tried this:
Mute the drums and the bass. Now we're dealing with mostly all the midrange instruments. Fine tune the volume and pans as required.
Then un-mute the drums and blend to taste.
Finally, un mute the bass and sit that in the mix.
I was really quite surprised on the last couple of my productions. They all needed fine adjustments and are now sounding a lot better.
Reason is (I think) is that if we mix 'all' together, the low end can get in the way and cloud our judgments.
