Discuss here mixing and mastering

I think the more information the better? Notes, references (other people's records for an aesthetic, your own mixes with what you did & didn't like?), yeah. If you've already done things that you're really happy with or that are integral to the sound, leave them on the stems rather than make them start from zero and recreate what you've done.

From what I've seen with friends, the trouble is only when the band and the mixer are going for different aesthetics and it's not communicated well. Also I guess revisions can be sticky, I would think that any mixer should be ok with one main revision pass and maybe some small adjustments after that, but I imagine most would charge more if it drags on and have some sort of agreement around that?

are you planning to search out a mix engineer? or do you know someone already? I'd just make sure they understand where you're coming from musically and/or you know and like stuff they've mixed already.
