Hey, metalheads! Joe here, and today we’re diving deep into the evolution of metal—where it all began, how it split into different sub-genres, and the bands that paved the way for what we’re rocking out to today. Whether you’re an old-school fan or new to the scene, it’s always good to know where our favorite genre comes from and how it’s grown into the beast it is now. So, let’s crank up the volume and take a journey through the decades of metal!

The birth of metal: Black Sabbath and the early pioneers

It all started in the late 1960s when bands like Led Zeppelin, Deep Purple, and Black Sabbath began experimenting with heavier sounds. But it was Black Sabbath’s self-titled debut album in 1970 that really set the foundation. With Tony Iommi’s distorted guitar riffs and Ozzy Osbourne’s eerie vocals, they created a sound that was darker and heavier than anything the world had heard before.

• Why They Matter: Black Sabbath’s music introduced themes of darkness, horror, and the supernatural, which would become cornerstones of metal. Tracks like Black Sabbath and Iron Man weren’t just songs; they were anthems for a new genre.

The rise of heavy metal: Iron Maiden, Judas Priest, and the NWOBHM

By the late 1970s, metal was picking up steam, and the New Wave of British Heavy Metal (NWOBHM) brought a new level of intensity. Bands like Iron Maiden, Judas Priest, and Motörhead took the foundation laid by Sabbath and cranked up the speed and aggression.

• Iron Maiden: Known for their galloping riffs and epic storytelling, Iron Maiden helped establish metal as a genre that could tell complex stories. Albums like The Number of the Beast and Powerslave are classics that continue to influence bands today.

• Judas Priest: With Rob Halford’s powerful vocals and twin guitar harmonies, Judas Priest gave metal a polished, powerful sound. British Steel and Painkiller are albums that showcase their influence on heavy metal’s identity.

• Motörhead: Lemmy and company brought a punk attitude to metal. They blurred the lines between metal and rock, giving us a raw, fast-paced sound that was all about attitude. Ace of Spades is a track that remains an absolute banger.

The birth of thrash: Metallica, Slayer, and the Big Four

In the 1980s, metal took a turn for the faster and more aggressive with the rise of thrash. Thrash metal brought together the speed of punk with the heaviness of metal, and bands like Metallica, Slayer, Megadeth, and Anthrax became known as “The Big Four” of thrash.

• Metallica: Early albums like Kill ‘Em All and Ride the Lightning defined thrash metal. Metallica’s riffs were fast and precise, and their songwriting brought a new level of complexity to metal. Master of Puppets is still considered one of the greatest metal albums of all time.

• Slayer: Slayer took thrash to the next level with their relentless speed and dark themes. Reign in Blood is an album that set the standard for intensity in metal. Tom Araya’s vocals, combined with Kerry King and Jeff Hanneman’s ferocious guitar work, made Slayer the ultimate thrash band.

• Megadeth: Led by Dave Mustaine, Megadeth brought a technical edge to thrash. Albums like Rust in Peaceshowcased intricate riffs and politically charged lyrics that influenced countless bands.

• Anthrax: Known for their high-energy performances and unique blend of thrash and punk, Anthrax brought a sense of fun to the thrash scene. Tracks like Caught in a Mosh and Indians are still fan favorites.

The emergence of subgenres: Death Metal, Black Metal, and More

As metal evolved, it branched into various subgenres, each with its own unique sound and aesthetic. By the late ’80s and early ’90s, bands were pushing the boundaries of heaviness, leading to the birth of death metal, black metal, and more.

• Death Metal: Bands like Death, Cannibal Corpse, and Morbid Angel brought a level of brutality that was unheard of at the time. Death metal is characterized by deep growls, complex riffs, and themes of horror and violence. Chuck Schuldiner of Death is often credited as one of the founding fathers of the genre.

• Black Metal: Black metal emerged from Norway with bands like Mayhem, Burzum, and Darkthrone. Known for their lo-fi production, blast beats, and shrieking vocals, these bands created a dark and atmospheric sound that was both haunting and intense. Black metal’s aesthetic, with its corpse paint and pagan imagery, set it apart from other subgenres.

• Doom Metal: Taking the slow, heavy riffs of Black Sabbath to the extreme, bands like Candlemass, Pentagram, and later Electric Wizard and Sleep, defined doom metal. The genre focuses on slower tempos, crushing heaviness, and themes of despair and mysticism.

The rise of Nu-Metal and Alternative Metal in the ’90s and 2000s

By the mid-’90s, metal was going through another transformation. Bands like Korn, Limp Bizkit, and Slipknot introduced nu-metal, which blended metal with elements of hip-hop, electronic, and grunge.

• Korn: With downtuned guitars, aggressive vocals, and a raw emotional edge, Korn’s self-titled album became the blueprint for nu-metal. Tracks like Blind and Freak on a Leash brought metal to a whole new audience.

• Slipknot: Known for their chaotic live shows and masked personas, Slipknot pushed nu-metal into even darker territory. Their debut album is full of intense, rage-fueled tracks that captured the angst of a generation. Wait and Bleed and Spit It Out remain fan favorites.

Alternative metal also began to gain traction, with bands like System of a Down, Tool, and Deftones blending metal with experimental elements, complex rhythms, and unique vocal styles. This era showed that metal could be innovative and versatile, constantly evolving while staying true to its heavy roots.

Modern Thrash and the new wave of Thrash Metal

Thrash never really died, and by the 2000s, a new generation of thrash bands was on the rise. Bands like Municipal Waste, Warbringer, and Havok breathed new life into the genre, paying homage to the classic sounds of Metallica and Slayer while adding their own modern twists.

• Municipal Waste: These guys brought a sense of fun and energy to thrash, with fast-paced riffs and lyrics that often veer into the absurd. They’re a reminder that thrash is still alive and well—and still knows how to party.

• Warbringer: With aggressive riffs and blistering solos, Warbringer captures the spirit of old-school thrash while bringing in fresh energy. They’re proof that thrash still has plenty of life left in it.

The present and future: Where metal is headed next

Today, metal continues to evolve. Genres like metalcore, djent, and post-metal have carved out their own spaces, with bands like Architects, Periphery, and Deafheaven pushing boundaries and bringing new fans into the fold. Metal is more diverse than ever, and bands are constantly finding new ways to innovate while staying true to the genre’s roots.

• Metalcore: Bands like Architects, Killswitch Engage, and Parkway Drive blend metal with hardcore, bringing a new level of intensity and emotion. This genre has introduced metal to a whole new generation.

• Djent: Characterized by complex rhythms and heavy, down-tuned guitars, bands like Periphery and TesseracT have pioneered this genre. Djent is a reminder that metal can be both brutal and intricately technical.

• Post-Metal: Bands like Deafheaven and Russian Circles are blurring the lines between metal, shoegaze, and ambient music, proving that metal can be atmospheric and introspective.
