The year 1976 was crucial for the evolution of heavy metal, as landmark albums like Rainbow's Rising and Scorpions' Virgin Killer began to reshape the genre. Perhaps none was quite as important as Judas Priest's sophomore effort, Sad Wings of Destiny, which simultaneously took heavy metal to new depths of darkness and new heights of technical precision. Building on the hard prog of bands like Queen and Wishbone Ash, plus the twin-guitar innovations of the latter and Thin Lizzy, Sad Wings fused these new influences with the gothic doom of Black Sabbath, the classical precision of Deep Purple, and the tight riffery of the more compact Led Zeppelin tunes. Priest's prog roots are still readily apparent here, particularly on the spacy ballad "Dreamer Deceiver," the multi-sectioned "Victim of Changes," and the softer sonic textures that appear from time to time. But if Priest's style was still evolving, the band's trademarks are firmly in place -- the piercing, operatic vocals of Rob Halford and the tightly controlled power riffing of guitarists K.K. Downing and Glenn Tipton.

This foundation sounded like little else on the metal scene at the time, and gave Sad Wings of Destiny much of its dramatic impact. Its mystique, though, was something else. No metal band had been this convincingly dark since Black Sabbath, and that band's hallucinatory haze was gone, replaced by a chillingly real cast of serial killers ("The Ripper"), murderous dictators ("Tyrant"), and military atrocities that far outweighed "War Pigs" ("Genocide"). Even the light piano ballad "Epitaph" sounds like a morbidly depressed Queen rewriting Sabbath's "Changes." Three songs rank as all-time metal classics, starting with the epic "Victim of Changes," which is blessed with an indelible main riff, a star-making vocal turn from Halford, explosive guitar work, and a tight focus that belies its nearly eight-minute length. "The Ripper" and "Tyrant," with their driving guitar riffs and concise construction, are the first seeds of what would flower into the New Wave of British Heavy Metal movement.

More than any other heavy metal album of its time, Sad Wings of Destiny offered the blueprint for the way forward. What's striking is how deeply this blueprint resonated through the years, from the prog ambitions of Iron Maiden to the thematic echoes in a pair of '80s thrash masterpieces. The horrors of Sad Wings are largely drawn from real life, much like Slayer's Seasons in the Abyss, and its all-consuming anxiety is over powerlessness, just like Metallica's magnum opus, Master of Puppets. (Though this latter preoccupation doubtlessly had more psychosexual roots in Rob Halford's case -- witness the peculiar torture fantasy of "Island of Domination.") Unfortunately, Sad Wings of Destiny didn't have as much impact upon release as it should have, mostly owing to the limitations of the small Gull label. It did, however, earn Judas Priest a shot with Columbia, where they would quickly become the most influential band in heavy metal not named Black Sabbath.

Frontman Rob Halford has considered this to be Judas Priest's SGT. PEPPER, and it's easy to see why. The album expanded upon the group's debut by tackling a variety of styles, utilizing dynamics to striking effect, and establishing the essential guitar interplay between Glenn Tipton and K.K. Downing. "Victim Of Changes" may be forever known for its snarling riffs and Halford's startling final scream, but its subdued mid-section enhances the power of those elements. "The Ripper" offers up Victorian horror, while "Tyrant" and "Island Of Domination" thunder along with metallic machismo.

The album has it softer side, however, notably the neo-classical rock instrumental "Prelude," the melancholy piano ballad "Epitaph," complete with crooning vocal harmonies, and the semi-acoustic existential contemplation "Dreamer Deceiver," a long-lost gem in the band's large oeuvre. Frankly, every track on this album is a winner, and SAD WINGS OF DESTINY would become the first of several albums from Priest that would forever transform the world of heavy metal.
