This cd, like Metallica’s “Master of Puppets” was re-mastered by DCC and sounds just as awesome. I know many metallifans are skeptical about purchasing these re-masters, but to my ears, the superior sound quality is there and is noticeable. I have owned a recording of this album (Ride the Lightning) on either record or cd since 1984, and have heard it probably a million times since then. When I heard the remastered cd version today, I heard many things that I hadn’t heard before. For example: The clarity in the intro solo by Hammett on “Fade to Black, the way Cliff Burton’s roaring, howling lead bass was meant to stand out on “The Call of Ktulu”, crisper drums and background vocals on “Creeping Death” and “Trapped Under Ice” are just some of the many sonic improvements on this cd. I understand that it’s a lot of money for a cd that most people who are fans of the band already own. But if you are a long time or serious fan/collector, this is a true must have. If you are on a tight budget, or think the standard cd sounds good enough, don’t bother. The cd also features re-packaging just like the original album (right down to the original megaforce records label in the upper right hand side of the back cover), though the differences are minimal from the standard issue cd, but noteworthy to the serious fan. I can only hope and pray that the horrendously recorded “And Justice For All” receives a similar treatment in the very near future.
