One of the things I commonly do in the studio is to make rough mixes as often as possible for the band. Once they have these there are a few things you can do to make your record better.
- Once you have a track of the rhythm section you can make mixes of these tracks and the members can load these onto their computers/iPods and practice to this tight track
- Load the rough mixes into your DAW and record ideas down to them. Having the clarity of studio recorded tracks can help you hear details and flaws in your parts you never heard before.
