Any Pantera song, just start at Fucking Hostile and work your way through.

My friend, have you heard of Snot?

Blood Eagle by Periphery is pretty damn heavy, but it may sound like noise on the first listen. The mix is dense, so it can take a minute to really digest what you're hearing.

Maybe Igorrr Or Electric Callboy Or Black Tongue Or maybe even Disavowed

If you like Noisia, we should be on the same page here...

The Hole Where Your House Was - Spor

Nothing Matters (Noisia Remix) - Mark Knight feat. Skin

Kingdom - Spor

Primordial - Audeka

Scarif - Black Sun Empire and Pythius

I Saw You - Black Sun Empire feat. Sarah Hezen

War March - Joe Ford

Life & Death - Rezz and Deathpact

Core - RL Grime

Amber - Ivy Lab

Some of those last few are hard in a different way, but anyway, should be at least one you like in there.

Try some of these

Heaviest Lamb of God - Vanishing, Desolution, To the End, Anthropoid

...unique, always energetic Devin Townsend - Mighty Masturbator (starts slow... wild ride), Kingdom, Liberation, Juular

Excellent melodies Brendon Small - Beastblade, On My Way

Sullivan King & Ray Volpe - The Dead March

Virtual Riot - Wallmonger

Crankdat - Ding Dong

shwirl, -Alow, & faux ivvy - kocham cię

Here's a few of my favorites, across a few genres. Each of these goes very hard in their own right. Some in unexpected ways, but they all have a really strong energy behind them.

Carpenter Brut - The Widow Maker
Carpenter Brut - Turbo Killer
GosT - Maleficarum
Perturbator - She Moves Like A Knife (NSFW thumbnail)
Heilung - Norupo
Nightwish - Noise
Abbath - Winterbane
Rotting Christ - Χ Ξ Σ (666)
Gojira - Stranded
BLVCK CEILING - WVFFLIFE
Machinae Supremacy - Player One
KMFDM - A Drug Against War
Mindless Self Indulgence - Witness

Then, if you have the time, these two are both some personal favorites of mine, but they're pretty long. But definitely worth the time, as they are not only absolutely beautiful songs on their own, but they also go very hard.

20:58: Nightwish - The Greatest Show On Earth (This is a live version of the song, and tells a story about the Big Bang and the birth of our universe, and has a special appearance by Richard Dawkins.)
14:07: Blind Guardian - And Then There Was Silence (This song is heavily inspired by The Iliad, the classic Greek poem by Homer.)

Have you considered Mick Gordon’s Doom soundtrack?

Off the top of my head there’s also “Hell Patrol” (Judas Priest):

Maybe the opening of “New Drugs” (Dead When I Found Her):

https://youtu.be/Z24aHbq5U_g

Or maybe “The Serpents of Eden” (Dawn of Ashes):

If it's energy you're looking for, I don't think I've ever seen much more of a "banger" than French band Shaka Ponk's "Palabra Mi Amor"

Dyers Eve by Metallica is a pretty overlooked song. It’s raw, aggressive and pretty deep. There may be heavier songs in this thread but the anger in this song really elevates it.

And there’s also most Pantera songs.

There is an interesting division when it comes to music that is perceived as "hard", and that is groove. Some just want music to sound evil and have harsh sounds, others require groove to feel the power. So, here are my recommendations with some groove:
Everything by Devildriver
Everything by Dethklok

Children of Bodom are you dead yet

Portrayal of Guilt is a heavy as fuck metal band that I really enjoy.

I've always really liked Du Hast, by Rammstein.

Pixies - Rock music: https://piped.video/watch?v=JbRbCtIgW3A

The Greatest Show On Earth, especially from the 5:46 mark (epilepsy warning - EXTREME flashing lights)

origin - expulsion of fury, venetian snares - ibantchivapulk

Great question, and I have two to suggest:

Cattle Battle - Atticus Ross and Trent Reznor. Builds with a punching industrial sound that's rife with Reznor's flavour, and climaxes hard with a moment of quiet before the impact.

Straight for the Sun/Desolation - Lamb of God. Intro is a quick breath and pure fury through Sun, then a seamless transition to Desolation which is a machine gun metal blast to the face.

I'm definitely saving this thread for later, personally I love the new Doom games soundtrack, or anything else from Mick Gordon. In a similar vibe I loved the soundtrack for a game called Cube, the guy that composed it (Marc A. Pullman) has an album that's great called Odious (other things by him are great also, but Odious is my favourite).

Really good suggestions already (Meshuggah, Spiritbox etc). But this list is not complete without: Rage against the machine - Bullet in the head, wake up, testify, sleep now in the fire. All great!

Shining. Specifically, the album Halmstad. Specifically, the first and last songs (the last is one of my favorite songs ever). A brutally heavy album about depression and suicide. Their whole thing (specifically their vocalist, Niklas Kvarforth) is trying to get people to harm themselves and commit suicide. Part gimmick, part truth.

Listen to Halmstad late at night when you're feeling down on life and it's just an insane experience.

Stop by !dsbm@lemmy.world if you want some more - I have a post with some starting bands.

Some other favorites of the genre are Make a Change... Kill Yourself (my favorite), Leviathan, and Xasthur.

Showbiz - Muse

Ænina - Tool

I Get It - Chevelle

Get to the Gone, Static-X
