Allan Tucker‬ (Audio Engineer: Elvis, Johnny Cash, Boston, John Lee Hooker, Judas Priest, Metallica): "The vinyl mastering engineers job was to just translate, not to make changes unless the vinyl couldn't handle it. So you don't change the low end or the high end. If the vinyl is blowing up you have to do something but otherwise it wasn't supposed to be particularly creative, but modern mastering is widely creative. We are suppose to jump in and taking a part, putting it back together again to come up with something that's new."
