For some reason when I'm in a club and it's loud as **** with shocking monitoring I find I have no idea what's going on and what I'm hearing yet all the mixes come out ok ... apparently ... god knows how I sure as hell don't ...
Ah well, the advantage you have in a club/on a loud rig, is that you can feel the beat. You can really feel when the beat is in and when it is out, the thump under your feet changes subtley.
