Review by Adam M on June 17, 2025.

This album changed the game for the band Celtic Frost by making their sound more avant-garde and influencing many band such Arcturus.  It is an important album because it tries different things like the song "Mexican Radio".  This was still a thrashy type of album with plenty of headbanger, but was more thoughtful and displayed a band taking risks and trying to be more innovative.

The musicianship on the album is strong a more developed style shining through and making this an interesting album.  The guitar work is thoughtful and ahead of its time.  The drumming is great, but it is Tom G. Warrior’s vocals that steal the show here.  He has a great voice and adds character to the songs.

The downside to the album is that is is not as aggressive and appealing as To Mega Therion and this does fall a bit flat.  It could be improved upon with more structuring of the album and a greater focus on the production values to be found.  This is still a noteworthy album and revolutionary to the style.

In conclusion, this is a very strong work and revolutionary to heavy metal.  The band would go on to produce Monotheist, another interesting work, but this is perhaps where the sound at their peak point.  Fans of Celtic Frost should check this out as should fans of interesting music.

If (ex) members of some of my favorite bands like Driller Killer, Gorgosaur, Deranged and Visions Of War combine forces to record a demo of what they themselves call Primitive Thrash Metal Khaos, you can be damn sure that I'm sitting up and paying attention. And fukk yesssss, this does not disappoint at all!!!

Imagine if you will, early Sodom getting into a fistfight with Sarcofago, while Bathory (from around "The Return") and "Deathcrush" era Mayhem are standing by the sideline, ready to sucker punch the both of 'em. Also hanging around, cheering on the chaos and confusion, are raw punk bands such as Disorder, Kaaos and Anti Cimex. This results in a scathing concoction of tremelo picked savage riffing colliding with a battering percussive attack that switches psychotic grinding velocity with pummeling d-beat stomp, while the bass guitar chainsaws its way through the high octane fueled thrash assault. On top of this comes the vicious vocal attack of Åsa, who delivers her lines in a gruff, throaty manner, not unlike Sabina Classen (Holy Moses) does, and this puts the icing on this rough 'n' gruff offering of, indeed, Primitive Thrash Metal Khaos. This is harsh stuff, and do I love this!!

The production follows suit: this is dirty, this is filthy, and sounds as raw as a truck load of ground beef. The best way to describe this is stripped down and chaotic, and I mean that in the best way possible. The overall proceedings occasionally sound like a blur, with the (completely natural) drums pushing the guitars in the back at times, but the beautiful thing is that it all makes sense! Music like this simply cannot exist with Coldplay production, it simply has to ooze chaos, grime and dirt like this. And even with the raw and messy production, it still manages to exude copious amounts of unhinged power and demented aggression. As stuff like this should do!

This is harsh, totally underground stuff, and I basically live for this shit. This is a huge dose of insane punked-up trend-free thrash metal dementia, that flies at your throat with only one intent, and that is to maim, maul and kill. I can only recommend this to those souls hardened in the blazing forges of the extreme music underground, but I'm more than convinced that they will have a blast with it!
