The mixes are the same song and they are using the same set of recorded tracks. They do have the option of not using all of them, so some may have a more "acoustic" feel. I guess the best thing would be to have the artist pick the version, but my concern was that he would pick the best sounding. I think the objective of WASH is to find a problem area for us to work on and discuss, not necessarily just master a track again. The client isn't realy technical enough to do this. In other words, if we all agreed that a particular mix sounds sibilant, narrow, unbalanced in some way, or some other particular problem, that would be the one to go for?
Thoughts?
