Even though
Master of Puppets didn't take as gigantic a leap forward as
Ride the Lightning, it was the band's greatest achievement, hailed as a masterpiece by critics far outside heavy metal's core audience. It was also a substantial hit, reaching the Top 30 and selling three million copies despite absolutely nonexistent airplay. Instead of a radical reinvention,
Master of Puppets is a refinement of past innovations. In fact, it's possible to compare
Ride the Lightning and
Master of Puppets song for song and note striking similarities between corresponding track positions on each record (although
Lightning's closing instrumental has been bumped up to next-to-last in
Master's running order). That hint of conservatism is really the only conceivable flaw here. Though it isn't as startling as
Ride the Lightning,
Master of Puppets feels more unified, both thematically and musically. Everything about it feels blown up to epic proportions (indeed, the songs are much longer on average), and the band feels more in control of its direction. You'd never know it by the lyrics, though -- in one way or another, nearly every song on
Master of Puppets deals with the fear of powerlessness. Sometimes they're about hypocritical authority (military and religious leaders), sometimes primal, uncontrollable human urges (drugs, insanity, rage), and, in true H.P. Lovecraft fashion, sometimes monsters. Yet by bookending the album with two slices of thrash mayhem ("Battery" and "Damage, Inc."), the band reigns triumphant through sheer force -- of sound, of will, of malice. The arrangements are thick and muscular, and the material varies enough in texture and tempo to hold interest through all its twists and turns. Some critics have called
Master of Puppets the best heavy metal album ever recorded; if it isn't, it certainly comes close. [In 2017 the band released a massive expanded edition of the album with a variety of physical package options, the most ambitious of which was an exhaustive box set that included a hardcover book, outtakes and previously unreleased interviews, three LPs, ten CDs, a cassette, two DVDs, a lithograph, a folder with handwritten lyrics, and a set of six buttons.] ~ Steve Huey
