by Patria

The genre of metal music is known for its intensity, complexity, and varied subgenres. Among these, the quest to identify the “heaviest” form of metal music is both intriguing and challenging. This article delves into the different criteria used to define heaviness in metal music, explores the history and characteristics of some of the most extreme subgenres, and ultimately aims to identify what could be considered the heaviest form of metal music.

1. Defining “Heaviness” in Metal Music

Volume and Intensity

Heaviness in metal music is often associated with high volume and intensity. The use of heavily distorted guitars, powerful drumming, and aggressive vocal styles contribute to a sound that is overwhelming and intense. Bands such as Slayer and Pantera set the standard for this form of heaviness with their relentless and ferocious approach to music.

Speed and Technicality

Another dimension of heaviness is the speed and technical proficiency displayed in the music. Fast tempos, complex guitar riffs, and intricate drumming patterns characterize subgenres like Thrash Metal and Technical Death Metal. Bands like Metallica and Death showcase high-speed riffing and exceptional musicianship, pushing the boundaries of what is considered heavy.

Atmosphere and Darkness

Heaviness can also be derived from the atmosphere and dark themes within the music. Doom Metal and Black Metal, for instance, often employ slower tempos and a sense of foreboding to create a heavy and oppressive atmosphere. Bands like Black Sabbath and Mayhem use haunting melodies and bleak lyrics to evoke a sense of darkness and despair.

2. Exploring the Heaviest Subgenres of Metal

Death Metal

Death Metal emerged in the mid-1980s, characterized by its brutal sound and themes of death, violence, and the macabre. Bands like Cannibal Corpse, Morbid Angel, and Deicide are known for their guttural vocals, blast beat drumming, and downtuned guitars. The relentless aggression and raw intensity of Death Metal make it a strong contender for the heaviest form of metal music.

Black Metal

Black Metal is known for its raw production, shrieking vocals, and atmospheric elements. Originating in the early 1980s, bands like Venom, Bathory, and Mayhem laid the foundation for the genre. The second wave of Black Metal, spearheaded by bands such as Burzum, Darkthrone, and Emperor, took the genre to new heights with their lo-fi recordings and themes of satanism, paganism, and anti-religion. The bleak and malevolent atmosphere of Black Metal contributes significantly to its heaviness.

Doom Metal

Doom Metal emphasizes slow tempos, heavy guitar riffs, and a general sense of despair. Influenced by the early works of Black Sabbath, bands like Saint Vitus, Candlemass, and Electric Wizard further developed the genre. The oppressive and suffocating atmosphere of Doom Metal, along with its often lengthy compositions, create a weighty and immersive listening experience.


Grindcore is an extreme fusion of Death Metal and Hardcore Punk, known for its blistering speed and chaotic sound. Bands like Napalm Death, Carcass, and Brutal Truth are pioneers of the genre, utilizing blast beats, distorted guitars, and politically charged lyrics. The sheer intensity and brevity of Grindcore songs, often lasting less than a minute, contribute to its reputation as one of the heaviest forms of metal.

Sludge Metal

Sludge Metal combines elements of Doom Metal and Hardcore Punk, characterized by its slow tempos, heavy distortion, and aggressive vocals. Bands like Eyehategod, Crowbar, and Acid Bath are notable for their thick, muddy sound and themes of suffering and addiction. The crushing heaviness of Sludge Metal is palpable, making it a formidable contender in the realm of heavy metal subgenres.

Brutal Death Metal

A subgenre of Death Metal, Brutal Death Metal takes the intensity up a notch with even more guttural vocals, technical riffing, and complex song structures. Bands like Suffocation, Dying Fetus, and Disgorge are known for their relentless brutality and technical prowess. The unyielding aggression and intricate compositions of Brutal Death Metal make it one of the heaviest forms of metal music.

Funeral Doom Metal

Funeral Doom Metal is a subgenre of Doom Metal that focuses on extremely slow tempos, mournful melodies, and an atmosphere of utter desolation. Bands like Skepticism, Esoteric, and Ahab create long, dirge-like compositions that evoke a sense of sorrow and hopelessness. The weighty atmosphere and glacial pace of Funeral Doom Metal contribute significantly to its heaviness.

3. The Pinnacle of Heaviness

To determine the heaviest form of metal music, it is essential to consider the fusion of elements from various subgenres. Bands that incorporate the brutal intensity of Death Metal, the atmospheric darkness of Black Metal, the slow tempos of Doom Metal, and the chaotic speed of Grindcore create a sound that is overwhelmingly heavy.
