On this day 40 years ago, thrash metal titans Slayer released their masterpiece Reign In Blood.
To this day, the record remains one of the most ferocious, influential and uncompromising albums in heavy metal history. Coming off the darker and more sprawling Hell Awaits, guitarists Jeff Hanneman and Kerry King deliberately pushed the band toward shorter, faster and more direct material, with Hanneman’s growing interest in hardcore punk helping shape the record’s relentless attack. Slayer entered Hit City West in Los Angeles with producer Rick Rubin and engineer Andy Wallace, and Rubin made the crucial decision to strip away much of the reverb that characterized metal production at the time, leaving the guitars, Tom Araya’s vocals and Dave Lombardo’s explosive drumming unusually dry, clear and immediate.
The band was exceptionally well rehearsed, allowing Lombardo to reportedly complete much of his drumming within just a few days, while Rubin essentially captured Slayer playing with near-live intensity. The finished album contained 10 songs in less than 29 minutes, an astonishingly compact running time that only amplified its impact.
Reign in Blood opens with one of Slayer’s defining compositions, “Angel of Death,” Hanneman’s controversial examination of Nazi physician Josef Mengele that begins with Araya’s unforgettable scream and erupts into nearly five minutes of controlled chaos. At the opposite end of the album is “Raining Blood,” whose ominous opening riff became arguably the most recognizable passage in Slayer’s catalog, while “Postmortem,” “Altar of Sacrifice,” “Jesus Saves,” “Criminally Insane” and the blistering “Necrophobic” demonstrated just how much the band could accomplish within remarkably short running times. The album’s lyrics and imagery generated controversy—particularly “Angel of Death”—but its musical execution drew enormous admiration from metal fans and critics and dramatically expanded Slayer’s audience.
Reign in Blood became the band’s first album to enter the Billboard 200, peaking at No. 94, while reaching No. 47 on the UK Albums Chart. It was certified Gold in the United States in 1992 for shipments of at least 500,000 copies. Exact lifetime sales have never been officially documented, in part because of changes in distribution, but longtime Slayer manager Rick Sales has estimated worldwide sales at more than two million copies, making that the most commonly cited figure rather than a verified current total.
Forty years later, Reign in Blood has transcended its original status as a landmark thrash record to become a blueprint for generations of extreme metal. Its combination of thrash-metal precision, hardcore-punk economy, Lombardo’s furious drumming, Hanneman and King’s riffing and Rubin’s stark production helped establish a vocabulary subsequently absorbed by death metal, black metal, grindcore, metalcore and countless other heavy styles. The album’s reputation has only strengthened with time: “Angel of Death” and “Raining Blood” remain essential Slayer songs, while the record’s astonishing lack of excess makes its 29-minute assault feel as dangerous and focused in 2026 as it did in 1986.
Its continuing importance is underscored by Slayer marking the 40th anniversary with special 2026 performances built around playing Reign in Blood in full. Four decades after its release, the album is not simply one of Slayer’s greatest achievements—it remains one of the defining recordings of thrash metal and a benchmark for how extreme music can be brutally aggressive, technically precise and unforgettable at the same time.
