Top 10 Best Sludge Metal Bands

Sludge metal is a controlled demolition. A crawling, seething fusion of doom's crushing weight and hardcore punk's raw nerve. You don't listen to sludge metal so much as survive it.

This list gives you the floor. Vote for the sludge bands that hit the hardest, drag the slowest, and ooze the most venom. You're not just picking favorites. You're staking a claim in a genre that never asked for polish, never cared for rules, and never stopped sounding like the audio equivalent of rusted machinery grinding itself to pieces.

If you're loyal to the old gods or flying the flag for newer purveyors of sonic filth, every vote pushes the sludge deeper into the spotlight it never wanted but definitely deserves.

The Top Ten

Mastodon

Mastodon is an American heavy metal band from Atlanta, Georgia. The band was formed in early 2000 and includes Troy Sanders on bass, Brent Hinds and Bill Kelliher on guitars, and Brann Dailor on drums. They are known for their complex song structures and blending of multiple metal subgenres.

I believe this should be in the top 10 because Mastodon just takes sludge to a whole new level. Their music has the technicality and precision of Northern industrial groups, the heart and soul of Southern groove bands, and that thick sludgy, dirty feel of Western sludge and stoner acts. They're also excellent in concert!

They are just a fantastic band. They have produced such a great variety of music while also maintaining a very distinctive and memorable sound. They simply have a unique tone that people can only strive to emulate. Their music peaked with the album "Crack the Skye," but their new album is still fabulous.
Melvins

The Melvins are an American sludge metal band formed in 1983 in Montesano, Washington. Known for their heavy and experimental sound, they typically perform as a trio, but in recent years have occasionally performed as a four-piece with two drummers. They are considered influential in the development... read more

The least predictable band of all time. It took me a good five years until I liked them, and I've loved them for 25 years. For the past decade, I can't even listen to anyone else (other than a little Death - RIP Chuck). Buzz conjures up riffs that are so heavy and so intense, and unlike anything heard before or by anyone after, that words cannot describe them. On drums, Dale Crover is the greatest rock drummer of all time (any genre). If you don't agree, go ask the guy you think is the greatest rock drummer ever, and he'll say "Dale Crover."
Melvins should be #1 on this list, and the next band should be listed at #23. The gap is deserved.

Without a doubt the best gig I have ever been to. The albums are as amazing and ridiculously cool as Buzz's hair.
Their don't care what you think attitude has always pulled me towards them. They do what they want and they shine like gods doing it.
Acid Bath

Acid Bath was a seminal American sludge metal band from Houma, Louisiana, active from 1991 to 1997. The band fused doom metal roots with influences from black metal, death metal, gothic rock, blues, folk, and country. Their unique blend of styles earned them a cult following despite their short career... read more

Agree with everyone: It isn't technical prowess, it isn't any one thing really. These people just happen to have a vibe together that is incredibly dark and at the same time artistic. By this, I mean they have a way of taking an idea apart and putting it back together in a way that conveys a meaning on various levels. Incredible.

After all these years of listening to music, not one band has stuck with me like Acid Bath has. Since discovering them roughly three years ago, there hasn't been a day I haven't listened to them, and I'm being serious. Their music creates such emotion that it's truly impossible to explain.
Crowbar

Crowbar is an American sludge metal band from New Orleans, Louisiana. Their music is known for being extremely slow, heavy, and brooding, with frequent fast-paced hardcore punk passages. The band was formed in 1990 by guitarist and vocalist Kirk Windstein and is considered one of the pioneering acts... read more

Heaviest band ever! Truly awesome songs like Conquering, I Have Failed, Mourn the Illusion, and All I Had I Gave. None heavier than Crowbar, still awesome after 25 years.

Nothing thicker. I will never understand why this band does not get more respect. Kirk, Crowbar, and Louisiana mud FTW.

Between them and Acid Bath, I don't think it can be decided. They both truly define sludge metal!
Eyehategod

Eyehategod is an American sludge metal band from New Orleans that formed in 1988. They have become one of the most well-known bands to emerge from the NOLA metal scene. Their music is characterized by heavy, abrasive sound and lyrics dealing with themes such as addiction and despair.

Just the absolutely best sludge band there is. I love many bands in this genre, but none can be compared to Eyehategod. The groove, intense feeling of despair, and overall darkness of reality just make them the best! It should not even be a contest.

Eyehategod is rhythmic, filthy, and listenable all at the same time. Their bluesy, sludge, and hardcore punk style of music is simply awesome. If you haven't listened to it, do.

The albums "Take As Needed...", "Dopesick," and "Preaching the End Time Message" are some of the heaviest and slowest Sabbathy-type southern sludge I've ever heard. Mike IX's vocals add to the discomfort. Download EHG's Live At Roadburn show off YouTube if you can. It's high quality (MP4) also!
Down

Down is an American heavy metal supergroup that formed in 1991 in New Orleans, Louisiana. The band's current lineup includes vocalist Phil Anselmo, guitarist Pepper Keenan, guitarist Bobby Landgraf, bassist Pat Bruders, and drummer Jimmy Bower. They are known for blending elements of doom metal, sludge... read more

Kind of an all-star band, but with only three albums, they earned their position among the best of the kind. From the southern "swampy" style of the Down II album to the great melodies and heavy guitars of NOLA and Over the Under, all the southern and bluesy styles combine with really heavy music and a frontman like no other.

I love NOLA. I like Melvins as well, but Eyehategod will be forgotten because of its small fan base. What a shame.

Down is just good. If you're looking for a more slowed down and bluesy sounding Pantera, Down is for you.
Neurosis

Neurosis is a post-metal band based in Oakland, California. They were formed in 1985 as a hardcore punk band. Over time, their sound evolved to incorporate doom metal, dark ambient, industrial, and folk music influences.

One of the all-time greats. But I think they are bigger than just sludge. They are so much more. So innovative and just all-around groundbreaking. There are few bands that will contribute to the world of music as Neurosis. They are just bigger than life. But I guess this is what will evolve when so many genius musicians get together and create magic.

This is one of the most important bands in the genre and should be on top! Not many bands can make the eerie moods that this band often makes, and not many bands can make you feel the darkness as this band does. One of the most important and most underrated bands in the genre! The best ever!
High on Fire

High on Fire is an American heavy metal band from Oakland, California, formed in 1998. The band was founded by guitarist and vocalist Matt Pike, who is also known for playing in the influential stoner doom band Sleep. Their music is known for its aggressive sound and blend of sludge metal and doom metal... read more

Excellent band. Give them a listen if you like it heavy.
Alice in Chains

Alice in Chains is an American grunge/alternative metal band formed in Seattle, Washington, in 1987 by guitarist and songwriter Jerry Cantrell and original lead vocalist Layne Staley. The band's most notable hits include "Man in the Box," "Down in a Hole," "Heaven Beside You," "No Excuses," "What the... read more

While Alice in Chains is more grunge than sludge metal, their self-titled album, commonly nicknamed "Tripod," is pretty much full sludge. The best grunge band of the era and my personal favorite band of all time.

This is one of the first bands that played sludge, yet they are in this place! These guys deserve number 1. There is no other band that can do sludge better than AiC.

I listen to everything from Sabbath to Cough. And I would definitely say that AiC has more in common with doom and sludge than the so-called grunge, which is just a silly catchphrase anyway.
Corrosion of Conformity

Corrosion of Conformity is an American heavy metal band from Raleigh, North Carolina, formed in 1982. Throughout much of its history, the band has featured guitarist Woody Weatherman, bassist Mike Dean, drummer Reed Mullin, and vocalist and rhythm guitarist Pepper Keenan.... read more

Why is this band only at No. 20? It should be at least in the top 10.

The Contenders

Baroness

Baroness is an American heavy metal band formed in Savannah, Georgia. The group's original members, including frontman John Baizley, grew up together in Lexington, Virginia. Known for their blend of sludge, progressive, and alternative metal, Baroness has released several critically acclaimed albums... read more

The Blue Record proves that sludge can be brutal and peaceful. Baroness plays insane music and deserves as much credibility as Mastodon, if not more, especially since Mastodon is moving away from the sludge genre while Baroness is only attempting to get better at it.

Definitely one of the best sludge bands out there. They have a foot in so many genres while remaining sludgy, and they help out a lot of the smaller sludge bands out there. Amazing, through and through.

Ever since I heard Purple, I've been addicted to these guys. They amaze me with every track.
Kylesa

Kylesa is an American sludge metal band that was formed in Savannah, Georgia. Their music incorporates experimentalism with heavy riffs, drop-tuned guitars, and elements of psychedelic rock. They released several critically acclaimed albums before announcing an indefinite hiatus in 2016.

I love all these bands, but I love my Kylesa the best.
Georgia seems to be taking over lately between Savannah and Atlanta.

Kylesa has to be one of the best sludge metal bands of all time. Spiral Shadow and Static Tensions prove that.
Iron Monkey

It takes a true master of extremity to come up with something that is suffocatingly heavy, yet catchy enough to stay in your head for hours. Under the glacial sludge, filthy crust punk bits, and gleefully hateful lyrics and vocal delivery, there is an undeniable groove (courtesy of drummer Justin Greaves) and a healthy respect for melodic riffing (courtesy of guitarists Dean Berry and James Rushby) that ultimately puts this band above the rest of the sludge metal legions.

These guys certainly pushed the intensity level of sludge to the limits. With migraine-inducing feedback, super heavy riffs, and vocals that sound entirely inhuman, it's wonderful stuff.
Weedeater

Weedeater is a stoner metal band formed in Wilmington, North Carolina, in 1998. Their sound features heavy, sludge-influenced riffs and gritty vocals. The group's most recent studio album, Goliathan, was released on May 19, 2015.

Pure, bubbling, oozing sludge. Dixon's screams and bass lines alone are enough to earn them a spot on the list. Pure southern filth.
Black Tusk

I love this band and I love their energy! I can't wait to see them again. Definitely one of my top favorite bands.

One of the most exciting live concerts I've ever seen.
Electric Wizard

Electric Wizard is an English doom metal band from Dorset, England. Formed in 1993, the band has released eight full-length albums. Their works Dopethrone and Come My Fanatics. . are widely regarded as landmark releases in the doom metal scene due to their dense, heavy sound and occult themes.

Dopethrone and Come My Fanatics are stellar. Electric Wizard captures a great heavy, sluggish feel with a lot of distortion, and (at least on the Dopethrone album) lots of reverb on the vocals. Very cool. Electric Wizard is considered by many to be one of the heaviest sounding bands within the genre.

Electric Wizard is Sludge Metal, Stoner Rock, and Doom Metal. In my opinion, they are the greatest Sludge Metal band of all time due to Dopethrone, which has become one of my favorite albums of all time.

Electric Wizard, to me, is the quintessential sludge metal band. They are also the best ever!
Buzzoven

Buzzoven is a sludge metal band from North Carolina, formed in 1990. The band played a major role in shaping the sludge metal genre along with New Orleans bands like Eyehategod and Acid Bath. Buzzoven also developed a reputation for chaotic and often violent live performances, which became a hallmark... read more

Pure southern hate. I will always love them.
Isis

It scares me that Isis is at 22. The riffs and atmosphere are perfect. Not to mention their thought-provoking lyrics. Everything about this band is amazing.

How is ISIS only at 24? I'll grudgingly accept Top 5, but Top 25 is unacceptable.
Sleep

Because it belongs at the very top with Electric Wizard.

They should be number one. They are the definition of sludge.
Red Fang

Red Fang is an American heavy metal band from Portland, Oregon, formed in 2005. The band consists of guitarist and vocalist Bryan Giles, bassist and vocalist Aaron Beam, guitarist David Sullivan, and drummer John Sherman. They are known for their energetic performances and humorous music videos.

Just great stoner metal. While everyone rocks out, I tip my cap to the rhythm guitar.
Bongzilla

Bongzilla is a stoner metal band from Madison, Wisconsin. As of 2015, the band had reunited after a six-year hiatus and embarked on a North American tour. They released a new studio album, Weedsconsin, in 2021.

Champagne when I'm thirsty, and.
Cult of Luna

Cult of Luna is a Swedish post-metal band from Umeå, founded in 1998. Their music often draws comparisons to other post-metal acts such as Neurosis and Isis. The band is known for its atmospheric sound and lengthy, layered compositions.

Really surprised I don't hear about them much. I think they are great.
Soilent Green

Soilent Green is an American metal band known for blending sludge metal, grindcore, and death metal elements. They formed in 1988 in the suburbs of New Orleans, Louisiana. Their music is characterized by its intensity and genre-crossing style.

They need to be higher. Not only do they fuse sludge with grindcore, they are one of the earliest NOLA sludge metal groups.

Sewn Mouth Secrets is a masterpiece.
Kingdom of Sorrow
Graveyard Rodeo
