I still haven't established a process on how I go about recording a song. However, it seems logical to start at pre-production and recording tracks. It's tempting to start mixing as I go, applying EQ and compressors, etc... as soon as I lay down a track but I try hard to avoid it. I keep reminding myself that mixing should start after the tracks have been cleaned, edited and when every piece of the puzzle is in place so that everything is mixed in context.
