The year 2008 was a good one for INTRONAUT as they signed onto a worldwide deal with Century Media Records and hit a home run with their amazingly brilliant “Prehistoricisms.” The band followed up with a successful touring schedule with Kylesa and Mastodon as well as the Great Indian Rock Festival in Dehli, India. Two years later INTRONAUT followed up that album in a most unexpected way with their 2010 release VALLEY OF SMOKE. There was a new direction a-brewing and the most noticeable aspect is the toning down the overall harshness and adding heavier doses of post-rock thus creating a thick atmospheric slick of post-metal with healthy portions of sludgery on the side. The band enjoyed the luxury of a stable lineup as well and on this one sees a cameo appearance of Justin Chancellor from Tool adding a second bass on the title track.

The opening track “Elegy” belies the direction of the album as it sounds like the signature progressive post-rock infused sludge metal that the band has been conjuring up from day one, complete with progressively constructed distorted riffs, shouted vocals and jazz-infused song structures. Starting with the second track “Above” Sacha Dunable seems to leave the harsh extreme vocals behind for the most part and focuses more on a clean atmospheric approach reminding me of the clean parts on later Enslaved albums in mood and dynamics. While the shouting pops up intermittently there is much more attention paid to the lighter aspects of the band’s sound. This is an approach they would even further on the following album “Habitual Levitations.”

After a perfect album like “Prehistoricisms” i hardly expected a repeat in its successful formula and i’m glad INTRONAUT didn’t try to simply recreate it. I have to admit that i was initially disappointed by the approach on VALLEY OF SMOKE upon first listen as they seem to be on the same trajectory as The Ocean or even Mastodon where they began their career as uncompromising heavy sludge outfits and have slowly drifted towards the more ethereal and atmospheric pastures of post-rock infused sludge metal but after a few listens this one does sink in and the progressive time signature workouts accompanied by seasoned musicians and the stellar production of Josh Newell only makes this one better after every spin. True that it will never dethrone what came before in my book but VALLEY OF SMOKE is still quite the sophisticated atmospheric sludge metal attack with lots of post-rock meanderings. Unlike “Prehistoricisms” which i can put on any time and fall into the musical ecstasy zone, VALLEY OF SMOKE requires me to be in the right mood to want to hear, but when i am this one does deliver the goods.

After a debut album and two EPs under their belt the members of INTRONAUT were only getting warmed up it seems. Another member change with Dave Timnick taking over guitar duties after the departure of Leon del Muerte seems to have been the necessary ingredient to grant INTRONAUT that magical prestidigitation to whip up and unleash their absolute wildest and most experimental album of their career. PREHISTORICISMS continues their reputation as an intellectual extreme metal band that seamlessly blends together elements of post-rock, psychedelia and crushing sludge metal brutality all laid out in the most satisfying of musical deliveries of the ages. This is the album that even made the critics go gaga and publications such as Decibel, Metal Maniacs, Outburn, Revolver and so on praised INTRONAUT as the next best thing and after hearing this musical masterpiece it isn’t too overly difficult to understand why.

The band goes about their usual business as before intermingling placid post-rock segments that once the listener is lured into a state of hypnotic bliss is sonically assaulted with catchy brutal riffs that sustain long enough to establish their dominance only to have the false sense of security shattered by unpredictable time signature changes that wend and wind the compositions through highly progressive head bangin' territory. While all the members are brilliant on their respective instruments, it’s worthy of mentioning the above and beyond the call of duty of fretless bass player Joe Lester who infuses the sound with the technical jazz fusion aspects. Equally vital to the new technical achievements is former Jane’s Addiction engineer Josh Newell, who blends together the seamless transitions between the soft and silky contemplative parts and the hardcore brutality by smoothing out any potential awkwardness between the contradictory styles on display.

While PREHISTORICISMS is undeniably the sound of INTRONAUT, the band went for broke and evolved every aspect of their sound to the next level. The compositions have been crafted carefully as to retain their signature sludge bombast all wrapped up with creative uses of slide guitar, fretless bass, highly technical drumming and ambient jazz-infused soundscapes. Timnick’s riffing style is top notch with its fuzzed fury graciously fusing with Sacha Dunable's aggressively screamed vocals with an emphasis on lyrical intellectualisms and concepts of the most primitive and atavistic aspects of the human experience. As mentioned, what really sets this release apart from its predecessors isn’t the excellent musicianship that is present on all of their material but rather the infusion of the jangly post-rock and jazz-infused technicalities. While throughout the majority of the album we are treated to brutal jarring dissonant orotundity, on the final track “The Reptilian Brain (Sleep, Eat, Shit, Fight, Fuck)” we are treated to a five part suite that begins like an Indian raga with sitars and tribal drums and slowly evolves into a 16 minute plus progressive behemoth that develops into a sludge metal monster that satisfies on all musical levels.

Not only is this my favorite INTRONAUT album but this is one of my favorite albums of all time. This is not only a desert isle pick but one that takes many of my disparate musical interests and throws them all together. The success lies not in the fact that these elements are all included but rather in how well crafted their inclusions are and how meticulously placed together in a logical sequence they exist while still finding improvisational space to deliver jarring surprises when least expected. The heavy down-tuned guitars and fretless bass work together in harmony while the percussion takes the listener on an exotic counter-journey. The rhythms, tones, timbres and tempos are all sorted out in a way as to allow the psychedelic and the sludge to not only coexist but to play together and dance the night away. This is highly recommended for anyone who craves mass quantities of intelligent design stamped upon every musical measure and imbued with exemplary musical maestrohood.

INTRONAUT The Direction Of Last Things

"The Direction Of Last Things" is the 5th full-length studio album by US progressive metal act Intronaut. The album was released through Century Media Records in November 2015. It´s the successor to "Habitual Levitations (Instilling Words With Tones)" from 2013.

Stylistically Intronaut have taken a slight step back to their heavier past and reintroduce harsh shouting hardcore vocals. A feature which was almost completely missing from their sound on the predecessor. Most vocals on the album are still mellow ethereal clean singing though (I´m often reminded of Paul Masvidal from Cynic). The instrumental part of the band´s music is still rooted in an adventurous playing rhythm section. Both drummer Danny Walker and bassist Joe Lester are very busy and quite inventive. The same can be said about the two guitarists/vocalists. The technical level of playing on this album is simply through the roof. There are strong jazz/fusion leanings in the music, but also sludge, post rock, mathcore, and progressive metal elements. The many styles combined it´s pretty hard to make a valid description of the band´s music, but atmospheric and technically well played progressive metal isn´t an all wrong label.

The material on the 7 track, 46:03 minutes long album is well written, intriguing, and consistent in both style and quality. The combination of heavier hard edged parts and atmospheric mellow sections works well for the band. Even at their most aggressive and busy Intronaut have a sophisticated calm to their delivery, which means the music on "The Direction Of Last Things" is sometimes closer to rock than it is to metal. Artists like A Perfect Circle, Tool, and late era-Cynic are valid references.

"The Direction Of Last Things" is a very well produced album, featuring a clear, organic, and powerful sounding production, which fits well with the atmospheric music. So that combined with the brilliant musicianship and the adventurous songwriting, make for an intriguing listen and a high quality release. That´s of course no surprise if you´re familiar with Intronaut´s preceeding releases, but it´s still worthy of praise that they can continue to keep the quality level of their output as high as they do here. A 4 star (80%) rating is deserved.

Originally this came out as their first demo titled “NULL - Demonstration Extended Play Compact Disc” that was recorded and released in 2005, but the band managed to impress the ears of the good folks at Goodfellow Records and this was repackaged, given a real album cover and released simply as NULL which became their very first release as an EP. The demo only had four tracks but an additional fifth track “Burning These Days” was included on the EP.

NULL shows just how much INTRONAUT have changed over the course of a decade, however much of their progressive take on the world of sludge metal is quite in tact on this first output. NULL reminds me a lot of the earliest Mastodon releases where their music is much more aggressive and fueled with adrenaline with fewer slower jazzy passages slipped into the mix but not totally devoid thereof either. For the most part Sacha Dunable’s vocals are growly and remind me a lot of Luc Lemay from Gorguts at this stage with very, very little clean vocals to be heard. The band are already adept at playing extremely complex riffs that form their signature melodic dissonance as Leon Del Muerte and Dunable deliver highly distorted and aggressive guitar riffs backed up by equally hardcore bass techniques of Joe Lester. Danny Walker has mastered the sludge metal drum sound but on this one he plays more aggressively and all the tracks are of a much higher tempo than much of the albums that follow. The time sigs and progressiveness is already in full play.

If you’re already an INTRONAUT fan don’t miss this debut EP for it’s as entertaining as any of the lot but it is true that the intricacies and complex song structures that they would really develop on “Prehistorians” are not quite so characteristic of their sound at this stage. This is a band that wants to blow the roof off the house pumping out fast and furious sludge metal without much of the atmospheric touches that they successfully weave into their overall trademark brand of sludge. While i wouldn’t call this their most essential offering i do find it one that i can’t live without and a highly enjoyable form of sonic torturous eardrum bombardment.

Since their debut on the progressive metal scene in 2006 with “Void,” INTRONAUT have only upped their game incrementally ever since pumping out one amazing album after another pleasing us progressive rock fiends who haven’t outgrown the extreme metal that sustains us. To the chagrin of some of us when an extreme metal band gets too soft, which was the case on “Habitial Levitations” where vocalist Sacha Dunable eschewed the growly extreme madness that makes extreme metal, well… extreme, is usually a sign that a band is on its way on the downside. Just something about shouted, growly and guttural vocals on top of highly distorted and anarchic sounding instrumentation just gives it that extra oomph.

Fears were being raised of going “Opeth” on that album that perhaps the band was toning things down a bit. Perhaps members were having babies, perhaps knitting sweaters for their wives, taking up home brewing or simply joining local cricket clubs. Well any such fears have been erased on their 2015 release THE DIRECTION OF LAST THINGS. Right from the very first glance of blackened birds swirling into the void reminds us of past glories that bring their magnum opus “Prehistoricisms” immediately to mind. The band was back to prove that they have indeed carved out their own brand of progressive atmospheric sludge metal and with this latest release they certainly have done so.

On THE DIRECTION OF LAST THINGS the band really takes all the best aspects of the past and borrows liberally from some of their influences and inserting them into their heavy distorted progressive madness that manages to combine totally new sonicscapes to escape within. Between the odd time signatures of the guitars of Dave Timnick and Sacha Dunable as well as the jazz-infused drumming talents of Danny Walker interacting on seemingly different worlds but threading it all together and the fretless bass maestrohood of Joe Lester, INTRONAUT simply has hit upon a sound and style all their own and with this latest release they only cement that sentiment into an already earned status placing them in the leagues of the influences heard on this album including the likes of Messhugah, Mastodon, Alice In Chains, Oceansize, Tool, Between The Buried And Me and beyond. However this band is certainly more than the sum of their influences thrown into a blender and randomly spewed out.

The beauty of INTRONAUT is how well they can cut and past and perfectly blend a furious storm of dissonance with various forms of abstract melodic development. They really know how to take the model of the structure of verse / chorus / verse / bridge / chorus thing and magnify that principle and into a much more complex mathematical equation, so while they are clearly in experimental mode they pay attention to keeping some sort of mental tracking system that takes patterns and repeats ideas enough as not to lose one’s bearings, however this is indeed complex music and an acquired taste that demands multiple listens to fully comprehend.

What really strikes me more than anything about this album is how well the songs are constructed. They really take the listener on an interesting ride keeping all the past INTRONAUT styles and instrumentation in tact but utilizing an abundance of riffing, vocal styles, pulverizing drumming and atmospheres just dripping in aggression, melancholy and extra-dimensional prowess. The production is also extraordinary as every little sound is animated and allowed to fulfill its potential. It always amazes me at some of the negative reviews and ratings that go with the instant gratification process that music has in general garnered over the decades. This album is one that does not bring that happy joy joy feel upon first listen although it is not without its hooks and addictive qualities, rather it is one of those albums that ratchets up the listener’s senses upon repeated listening. I’m finding this to be so much more satisfying upon repeated bombardments of my senses! While i understand this is truly a progressive metal band in the truest sense of the meaning, i don’t find superficial exposure to be adequate in the eternal art of “getting it”. This is music that took years to put together. Music that is to be worked for is some of the most satisfying music i have found and this definitely falls into that camp for even as an INTRONAUT fan i’ve had to pay special attention to the details.

This is highly recommended for all the obvious sludge metal freaks who like Isis, Mastodon, Baroness, Neurosis and beyond but there are many progressive aspects i am hearing that bring Enslaved, Gorguts, Alice In Chains, Tool and even Meshuggah to mind. Well worth the price of admission and one that only gets better the more you listen to it, at least that has been the case for me. Perhaps not quite as perfect as “Prehistoricisms” but definitely a close second in their discography for me and one that i am convinced will only garner more attention over the time as these days we are inundated with so much music that it’s impossible to digest it all. What a wonderful problem to have!
