How often do you do it? In a dense mix of quadruple tracks guitars, bass and drums in a rock tune that has that going on for about 8 bars before the vocals come in..do you subtley drop the bussed guitars down in volume to make room for the vocals to stand out?....Speaking of which, how do you carve out sound to make a rock tenor vocalist not sound like it's fighting with the crunchy rhythym guitars for space, other than panning? Thanks.
