Greatest Tech/Extreme Prog Metal Bands

Tech/extreme prog metal is a subgenre of progressive rock with roots in Extreme Metal or strongly influenced by it. The style developed by the end of the 80s in the Thrash Metal scene when a number of bands stretched the boundaries of their sound by including elements from Progressive Rock. Death Metal followed a similar path in the 90s and by the 2000s, also Black Metal and Metalcore saw an increasing amount of bands taking in Prog influences. Here are some of the bands and artists of the genre that I consider the best.

The items for this list are based off of the classifications used on the Progarchives website.
The Top Ten
Opeth Opeth is a Swedish progressive metal band from Stockholm, formed in 1990 by David Isberg, who invited Mikael Åkerfeldt into the band as a bassist. Isberg ended up leaving the band, which led to Åkerfeldt becoming the band's vocalist, guitarist, principal songwriter, and driving force... read more

Atmospheric, dark progressive death metal at its finest. The songs often have elements of beauty among them, courtesy of Mikael Åkerfeldt's incredible voice, capable of producing chilling death growls and some incredible clean passages. Their sound is also quite diverse in this area, with some early works sounding more like melodic black metal along the lines of Dissection. They have also gone the opposite way and made some fairly decent standard prog rock, along with the amazingly haunting Damnation.

Death Death was an American death metal band formed in 1983 by Chuck Schuldiner. Death is considered to be one of the most influential bands in heavy metal and a pioneering force in death metal. Its debut album, Scream Bloody Gore, has been widely regarded as the first death metal record, while the band's... read more

While their early albums were pure death metal, from Human onwards, they began adding more progressive elements to their music. These albums are where I personally find that Death shines brightest, as the instrumentation is incredible for the most part, transitioning from section to section extremely clearly. They constantly maintain a high level of intensity, providing a fairly unique sound in death metal, especially when considering the cleaner production compared to most death metal bands.

Gojira Gojira is a progressive metal band from Bayonne, France. The band was known as Godzilla until 2001. Gojira is composed of Joe Duplantier on vocals and rhythm guitar, his brother Mario Duplantier on drums, Christian Andreu on lead guitar, and Jean-Michel Labadie on bass.

What this band does best is creating amazingly heavy music, with a particular focus on bone-crushing riffs. The production and mixing give their music an extremely large, spacious feel, further increasing the intensity and making each note feel incredibly impactful and powerful. They also weave in some more emotional, beautiful moments in songs such as Global Warming and The Gift of Guilt.

Between the Buried and Me Between the Buried and Me is an American progressive metal band from Raleigh, North Carolina. Formed in 2000, the band consists of Tommy Giles Rogers, Jr.

The way this band transitions from one riff or section to another seamlessly, no matter what the change is - ranging from heavy death metal breakdowns to bluegrass - makes it an incredibly interesting listen. Each song is incredibly dynamic, going from riff to riff extremely quickly, while still keeping it sounding excellent throughout. The clean sections also tend to be great, breaking up particularly intense parts and bringing in some amazing melodies in the process.

Ne Obliviscaris Ne Obliviscaris (Latin for "forget not") are an extreme progressive metal band from Melbourne, Australia, formed in 2003.

I politely disagree that what they do isn't incredible:

1. They perform duets between clean and unclean vocals - the clean and harsh vocalists sing simultaneously, harmonizing their vocal lines. Can you name another prog metal band that does this?
2. Many metal bands use violins occasionally and usually in the background as part of the arrangement. But Ne Obliviscaris uses violins all the time and offers dueling solos between a guitar and a violin, and sometimes between a violin and a bass.
3. Their composing skills are incredible, and one of their songs is studied at a Music Conservatorium for its composition.

Gorguts Gorguts is a Canadian technical death metal band from Sherbrooke, Quebec. The band was formed in 1989; its only constant member has been Luc Lemay.

Extremely challenging, dissonant music in every way, like what Captain Beefheart would have sounded like if he wrote death metal. The songs seem to transition every 5 - 10 seconds, introducing new, heavy riffs. It almost feels like it doesn't work properly, yet it always manages to come together, providing the listener with a feeling that is hard to create, often leaving them slightly off-kilter due to the music's unpredictability.

One of the least accessible metal bands ever, which is a compliment in a metal context.

Meshuggah Meshuggah is a Swedish progressive metal band from Umeå, formed in 1987. They are often considered the fathers or founders of the djent metal sub genre due to their use of downtuned guitars. They are also known for their song “Bleed”, which is known for its extremely complicated instrumentation,... read more
Nile Nile is an American technical death metal band from Greenville, South Carolina, United States, formed in 1993. Their music and lyrics are inspired by Ancient Egyptian/Near Eastern mysticism, history, religion, and ancient art, as well as the works of H.P. Lovecraft.
Obscura Obscura is a technical/progressive death metal band from Germany, founded in 2002. The band became prominent when members of Necrophagist and Pestilence joined Steffen Kummerer to release the critically acclaimed second full-length album, Cosmogenesis. The band was named after the Gorguts album Obscura... read more

If you want to hear how to correctly incorporate jazz elements in extreme metal, listen to their song Diluvium (2018). The jazz elements don't make the song lose its metal feel, tempo, or technicality. I needed to say this because many metal bands who try to incorporate jazz often end up sounding like bands playing cheesy lounge music.

Cryptopsy Cryptopsy is a Canadian technical death metal band from Montreal, Quebec, formed in 1988. The band has sold over 300,000 records.

The Newcomers

? Vektor Vektor is an American progressive thrash metal band from Tempe, Arizona. The band was formed under the name Locrian around June 2003, but changed their name to Vektor in 2004.
? Haken Haken are an English progressive metal band formed in 2007 by multi-instrumentalist Richard Henshall, guitarist Matthew Marshall, and vocalist Ross Jennings.
The Contenders
Enslaved Enslaved is a Norwegian extreme metal band formed in Haugesund in June 1991. They are currently based in Bergen, Norway.
Voivod Voivod is a Canadian heavy metal band from Jonquière, Québec. Their musical style has changed several times since the band's origin in the early 1980s. The band's current line-up consists of Denis "Snake" Bélanger, Daniel "Chewy" Mongrain, Dominique "Rocky" Laroche and Michel "Away" Langevin.

I haven't listened to much of their work so far, but I really love what I've heard (specifically Nothingface). I've heard them described as Gentle Giant if they went metal, and I can somewhat see the comparison. Both bands favor shorter stretches of music filled with many different ideas and embrace the quirkier side of their respective genres.

Spawn of Possession Spawn of Possession was a technical death metal band from Kalmar, Sweden, founded in 1997. In 2017, the band announced their split up via their Facebook page.
Leprous Leprous is a Norwegian progressive metal band formed in 2001 in Notodden, Norway. The band gained prominence as the backing band for former Emperor frontman Ihsahn's live shows.

Each album they make is quite difficult to get into, and each is different from the other, but always very complex and interesting. The band always sounds very fresh and innovative, never seeming as if they've hit a roadblock. Some albums focus more on vocal harmonies and a slightly symphonic sound, while others delve deep into extremely dark atmospheres, clearly maturing with each album.

Mastodon Mastodon is an American heavy metal band from Atlanta, Georgia, formed in early 2000 and composed of bassist Troy Sanders, guitarists Brent Hinds and Bill Kelliher and drummer Brann Dailor.

While a couple of their later albums are somewhat questionable, in general, this band has released some incredible material. Their music ranges from extremely heavy, chaotic, and aggressive to sludgy and more prog-focused. The technicality they display provides for some great songs, especially in terms of the riffs the band comes up with.

Horrendous Established in 2009, Horrendous is an American metal outfit with a distinct approach to death metal. Their music features a melodic undercurrent, merging it with technical aspects to yield a nuanced sound. With a discography that has received praise from critics, the band has carved out a unique space... read more
Sikth

While I'm not a major fan of most 'djent' bands, I find Sikth to be the massive exception due to their unhinged sound, similar to System of a Down if they decided to become heavier. The vocal work in particular stands out, being quite bizarre in general. Their more experimental moments also separate them from other 'djent' bands, including some elements of eerie atmosphere and the like.

Beyond Creation Beyond Creation is a Canadian technical death metal band from Montreal, Quebec. They are currently signed to Season of Mist records.
Blotted Science Blotted Science is an instrumental technical metal supergroup formed in 2004. It is headed by Ron Jarzombek, bassist Alex Webster and drummer Hannes Grossmann.
Animals As Leaders Animals as Leaders is an American progressive metal band from Washington, D.C. It is composed of guitarists Tosin Abasi and Javier Reyes along with drummer Matt Garstka, having been formed by Abasi in 2007. Their musical style has also been described as djent.
