I'm sure this has been discussed before [though I can't find it], but I'm curious to know what differences exist between original US LP titles and their foreign counterparts. For the sake of simplicity, by "foreign" I'll say "Japan." OK, so Japan wants to issue a current Eagles LP in, let's say, 1974. What tape are they sent? Would that tape be the same generation as the tape used for the US LP issue, or would it be one [or more] generation down? [Were all US LPs manufactured using first-generation tapes or were safety copies sometimes used?] Was it ever the case that Japan would be sent the actual stampers as manufactured in the US? What advantages, other than superior vinyl, are there with Japanese issues if indeed a lower generation tape was sourced? Is it a case-by-case situation where occasionally the Japanese mastering was superior to that done in the US such that even with a lower-generation source tape the end results may be superior to the original US issue?
