I remember that before It's Only RnR came out, I heard that the master tapes were being flow someplace to be mixed once again. Does anyone know whether there was some kind of problem with the mixing of the album, or is making several attempts at doing a final mix a common practice? Another question, when an album says "mastered by" just what is the job of the person that creates the master, and what kind of a process is involved in doing so? Thanks in advance for adding to my shallow depth of knowledge.
