Heavy Metal ‘86
What makes 1986 the greatest year in heavy metal music?
1986 is widely considered the most significant year in the history of heavy metal, and for good reason.
It was a pivotal year that transformed heavy metal as it emerged from the shadow realm into the mainstream and shredding was elevated to an artform.
This metal metamorphosis was underpinned by the release of four seminal albums in the same year: ‘Master of Puppets’ by Metallica, ‘Raining Blood’ by Slayer, ‘Somewhere in Time’ by Iron Maiden, and ‘Peace Sells…But Who’s Buying?’ by Megadeth.
2026 marks the 40th anniversary of these albums, signifying a major milestone in the evolution of heavy metal that will be celebrated by metalheads around the world. For many, 1986 remains the pinnacle of greatness for the genre.
Birthed in the late ‘60s by British heavyweight bands Black Sabbath, Deep Purple, and Led Zeppelin – the unholy Trinity of rock – heavy metal exploded throughout the ‘70s, though was still largely rooted in the blues rock origins of its progenitors.
By the early ‘80s, the New Wave of British Heavy Metal had taken over. Bands like Iron Maiden, Def Leppard, Judas Priest, and Motorhead incorporated a much darker and aggressive aesthetic.
Still in its infancy as a genre, heavy metal was beginning to take its first major steps as incoming bands expanded on the established sound. The music got progressively harder, sharper, and much, much faster.
Across the Atlantic, the sounds of British heavy metal enlivened the youth of America, and a new generation was making its mark by taking the genre to its extremes. In Pasadena, southern California, the blistering guitar work of Eddie Van Halen rewrote the rules about what the instrument could do, aided by advancements in guitar technology like the Floyd Rose tremolo system.
Meanwhile, in the Bay Area of northern California, something else entirely was brewing. A new breed of metal was being pioneered, inspired by NWOBHM and played with blazing speed and technical precision. Speed metal, the early forerunner to thrash, was taking shape across the West Coast.
The region produced three of thrash metal’s ‘Big Four’ bands: Slayer, Metallica, and Megadeth; the fourth, Anthrax from New York, were one of the first thrash metal bands to emerge from the East Coast.
Thrash, and heavy metal in general, dwelled on the fringes of musical taste during the early ‘80s. Its aggressive, unrelenting sound and explicit lyrics about Satanism, war, and death attracted the attention of concerned parents, religious groups, and lawmakers.
The rise of thrash coincided with ‘the Satanic Panic’, a moral panic about widespread abuse of children by organised Satanic cults. Thrash metal bands became an easy target for unsubstantiated fears about their music encouraging ritual abuse, self-harm, occultism, murder, and suicide.
Flinders Dolomite is a household name in the agricultural industry and has been the Dolomite of choice for more than 130 years.
Bands like Slayer, which employed overt Satanic imagery, were accused of corrupting the youth through their dark and dangerous music. Some claimed bands inserted secret messages in their albums through backmasking that, when played backwards, reveal a Satanic message.
The hysteria led to the establishment of the Parental Music Resource Centre (PMRC), which was co-founded by Al Gore’s wife, Tipper Gore. The committee prejudicially targeted bands for so-called explicit imagery and themes in their music, producing a ‘Filthy 15’ list, which included bands like Judas Priest, Twisted Sister, and Prince. The PMRC were instrumental in the introduction of the parental advisory sticker placed on records containing explicit content.
While the PMRC’s pearl-clutching witch hunt was successful in feeding the fears of parents across the US, it did little to deter the bands or their fans. If anything, it gave thrash metal the mass media exposure it needed to make the cross between underground scene and mainstream success.
Come 1986, and under the shadow of the PMRC and its machinations, three albums are released that will define the sound of thrash metal and be immortalised in metal lore. In March, Metallica unleashed their third album ‘Master of Puppets’, an album that requires little to no explanation. Aside from its well-documented cultural significance, it is the last album to feature bassist Cliff Burton, who died in a bus accident while on tour in September that same year.
Burton’s death on 27 September is macabrely bookended by the release of Megadeth’s second album ‘Peace Sells… But Who’s Buying?’ (25 Sept.) and ‘Somewhere in Time’ (29 Sept.), the sixth album by NWOBHM lords Iron Maiden.
Both albums are significant in their own right: ‘Peace Sells…’ was the first major label release for Megadeth and solidified Dave Mustaine as a force in metal outside of his early work with Metallica.
‘Somewhere In Time’, on the other hand, marks a shift in direction for Iron Maiden who at this point were ruling the world with a relentless touring schedule. Exhausted from endless touring, vocalist Bruce Dickinson contributed very little to the album, most of his ideas rejected by the band. ‘Somewhere In Time’ is notable for its extensive use of synthesisers, a first for Iron Maiden. The only song not to feature synths is the single ‘Stranger in a Strange Land’.
But the most brutal entry came in October when Slayer opened a Hell gate with the release of their third studio album ‘Reign In Blood’. This album is the epitome of sonic brutality, pummelling the eardrums and establishing Slayer’s undeniable presence that remains to this day. Clocking in at just under 30 minutes, ‘Reign In Blood’ is an undisputed masterpiece of thrash metal.
Together, these albums form a watershed moment in heavy metal history. Although released in 1987, Anthrax’s third album ‘Among the Living’ is often included in the count. It is dedicated to Cliff Burton; Anthrax was the opening act for Metallica when the fatal bus accident occurred. It also represents the band’s ascension to the ‘Big Four’ of thrash metal and is considered among the strongest thrash metal albums of all time.
The following years saw thrash metal achieve its commercial peak, until the early ‘90s when, once again, the musical tides shifted and metal was usurped by the next new thing: grunge. Big hair and spandex gave way to flannelette and nihilism as Generation X took control the zeitgeist.
Industry interest turned away from Sunset Strip towards Seattle, where the alternative music scene was taking root with bands like Nirvana, Pearl Jam, Soundgarden, and Alice In Chains. A new voice for a new generation.
But metal maintained, its spirit living on throughout the ‘90s in legends like Dimebag Darrell of Pantera, who was deeply inspired by greats like Randy Rhoads. Ozzy Osbourne experienced a resurgence as he began working with Zakk Wylde, another ‘Rhoads’ scholar, and there was renewed interest in metal as it transformed immensely throughout the decade.
The late ‘90s brought the influx of nu metal, and bands like Korn and Limp Bizkit became the taste du jour of the new millennium, writing a new chapter for the genre. Though the sound continued to change, the spirit of heavy metal remained untouched.
And that spirit is maintained in any number of contemporary bands that count Metallica, Slayer, Megadeth, and Iron Maiden among their primary influences. Even today, 40 years later, these albums continue to find newfound relevance with incoming audiences.
Ultimately, 1986 stands as heavy metal’s defining inflection point: a year when the genre’s underground intensity, technical ambition, and cultural controversy converged into records that set the benchmark for thrash and reshaped metal’s mainstream profile. With ‘Master of Puppets’, ‘Reign in Blood’, ‘Peace Sells… But Who’s Buying?’, and ‘Somewhere in Time’ turning 40 in 2026, their enduring impact is not just nostalgia – it’s living proof that the innovations of that moment continue to reverberate through every new wave of heavy music.
