Eh... Sort of. But really it should all work together before mixing even starts. Not just sorta' work. It should be almost radio-ready aside from the fact that it is spread out over 24 tracks.
When you do go in for EQ mixing improvements, don't go soloing every track listening in isolation to cut out what is bad. You have to listen all at once. I know TyphoidHippo didn't mean that you should solo, I'm just clarifying.
Actually, I don't think it would matter if the track was soloed or not - I wasn't clear with exactly what I was saying, and I see that now. I was advising him to notch out those nasty resonant sounds that just somehow manage to find their way into recorded audio.
As far as actual mixing, yea, of course - don't do that one track at a time, and some things will benefit from gentle boosts, some from cuts, some won't benefit from any EQ at all. I just kind of glossed over that with "the song will mix itself" - it should be pretty intuitive what needs to be done if the tracks are all in tune, sound good, and have all their nasties notched out. I didn't understand the parametric sweep technique for a long time, and once I found it... well, everything just made sense - take all the quirky crap-sounds out of each track, and that naturally just leaves room for non-crap sounds of other tracks - I wouldn't even consider it part of mixing, honestly - immediately after tracking something, I sweep through and notch out anything that makes my ears bleed when boosted 10 db with a really narrow Q. I'm not talking about doing something dramatic to the track like a high-or low pass, or anything that would actually be a mix-decision. I'm talking about notching out the very-narrow bands of noise that just aren't musical, I don't honestly know exactly what causes them - but they sound *terrible* and they wouldn't be good in any mix, for any reason. There's no way to tell they're even there without doing the "parametric sweep" technique. Of course, after notching them out, and ABing back and forth - it's like "oh wow - that was just a horrible noise - and now it's gone".
It's very rare for some recorded source to not have at least one... but I find that if there's more than two or three hotspots of "crapness" when doing the sweep, the track needs to be re-recorded with a different mic, or in a different room, or something - something's just not working. That link I posted explains the idea quite exhaustively.
