Funny you mention it that way, because so many times I've seen shows ( large AND small) where the guitars and or drums were drowning out the vocals. Most Metal bands seem to think that the dual bass drum rapid machine guns are king, but I can't hear a word they are screaming. I can account for taste, and I know I have my "thing", but within reason, the balance is not equal when you are selling a lyric or a melody. Solos are always pumped up ... the lead always gets the nod ... same with our arranger world.

I'm not trying to argue with you - in extreme amounts, I agree that imbalance is wrong too, but given the mechanical, repetitive nature of the backings and the live nature of the lead - I think the lead needs to be emphasized. In my mind, that's the proper balance, but I agree - balance IS important.
