No James could sing of course..and I love his 80s voice, but to be honest I doubt he actually had much idea of what he was doing in the 80s. I don't think he gave stuff like vocal technique, control, vibrancy, range etc much thought. He started experimenting and working on that during The Black Album sessions which made him capable of singing stuff like Nothing Else Matters and The Unforgiven...I'm not sure that Bob Rock taught James to sing. He may have polished things a bit, but James sounded pretty good way before that. Take Welcome Home, for instance, or Fade to Black, or One. I don't think he sounded any worse there than on Enter Sandman (god, this song is so overrated!) or Turn the Page or any of the later crap.
