Mark, did you remove the links you posted today? I saw them at work, but they seem to have disappeared.
@Mick:
What I meant to say (and I think Mark's intention was the same) is: Don't do things just because someone told you it has to be done that way. Try and decide for yourself what works and what doesn't.
Low cuts, for example, are something very dangerous IMO. If you overdo them, you will end up with a sterile, cold/artificial sounding mix. Low cuts are a bad habit anyway. If you have to get rid of some of the low end, better use a shelving filter. If you use low cuts the corner frequencies will pile up.
Low cuts will also remove the lower frequency harmonics that are an essential part of the natural sound of a specific instrument.
Another bad habit IMO is master bus compression. It may certainly work well for some music styles, but it is not a splendid idea in general. Again: Try things, but trust your ears!
LCR panning is another poor practice (again IMO, of course). I listened to a couple of songs at work today, and some of them were mixed that way. They sound really strange and unpleasant on head phones. I would not recommend doing that at all. Your mileage may vary.
Videos and recommendations (like mine too, of course) are good to extend your view, but we must never forget that there are no rules that cannot be broken. What sounds good is good. And different people have different ideas of what sounds good and what doesn't.
The big guys don't all agree to each other either. And for a good reason.
Regards,
Steffen
