Try this...on a track that you're at the very final mixing stages with,
don't listen to it for 24 hrs or so. Then come back and bring the mix
up again - BUT - keep your monitoring volume *very* low.
Just low enough to make it a bit frustrating! Tease yourself
Now your challenge is to make the track listenable *without*
turning up your monitoring. I'm not saying just compress the
hell out of it - cos it won't sound good, and we're going for
listenable - just "louder" so that you can enjoy the track again.
Once you've squeezed frequency bands you never even knew existed,
and been through your whole arsenal of toys, dump it to CD/WAV
and listen again, this time at higher volumes. Doesn't it sparkle
a lot more? Don't a lot of the most positive instruments take centre
stage rather than the atmospheres and embellishments?
Of course now you can go back and more traditionally hone the
mix you've just left with. But I'll bet you a few beers that you'll
have a less cluttered, more powerful sounding track.
