Mutagenic Host is a death metal band from London, England who hit the scene with their debut demo in 2023. They are ready to reveal their true power with “The Diseased Machine,” their debut full-length album.
This is quite the impressive debut album! It’s an album of balance, in every way. The production/mix nails down how to present a death metal album with real weight but still package it in modern sound without compromising any of the genre’s brutal elements. The tempo isn’t too fast or too slow. With that said, however, they aren’t comfortable just throwing the songs out in a mid paced display either. The speed of the songs vary when needed and will sometimes change several times within the songs themselves.
That’s another aspect of the album I really enjoy: it changes and refreshes itself in a way that feels very natural, very organic but those changes aren’t abrupt—this isn’t tech death or prog but death metal that seeks to march to its own drummer. Speaking of which, George’s drummers are utterly engaging from beginning to end. Together with bassist Swales, the two offer a very robust rhythm machine.
The album begins with “Neurological Necrosis,” and around the 21 second mark, Jack and Dan throw out chunky riffs that slide into a groovy, highlighted by the bass and drums. The song very quickly fires on all cylinders and gets knocked up to the next level by vocalist Ash Moore. Its barks and growls are also very balanced, finding a good mid-range between highs and lows.
Blitzkriegs and whisplast instrumentation push the song to the edges of extreme before introducing thick grooves and a surprisingly catchy cadence. The last minute or so really impresses, the guitars/bass grinding out a slow crush that lets their insane tone loose.
“The Twisted Helix,” introduces a little melody into the mix, yet another element the band isn’t afraid to embrace but only when needed. Even as early into the album as this song, the band makes it obvious they put the song first. There isn’t anything just thrown to wall to see if it sticks—this is thought out death metal where every note has its place in the given moment.
The riffs on this song are insane! They find a sweet spot early on with the bass and just groove it out, riding alongside the vocals. It’s an effective way to fill up the atmosphere with pulverizing notes without going overboard. Just after the halfway mark, the band does go overheard and lashes out with stunning fury. This song just gets heavier and heavier, never stopping for a second.
“Organometallic Assimilation,” is one of my favorites on the album. The beginning moments have the drums build up the tension, which is fully grasped by the guitars. The riffs are more intricate here with a lot of little details and hooks that grabbed me hard. The upkick in tempo after the two minute mark is a burner with insane focus but the instrumentation is still discernible, not simply just speed for speed.
“Incomprehensible Methods of Slaughter,” is one of the more grimy, disgusting songs on the album. From the opening growl to the dirty riffs, this is one sick as hell song. Despite that, it’s catchier than it has any right to be. This is one of the more zeroed in songs, in terms of total death metal devastation. In particular, the bass and drums are demanding of the senses.
The final song, “Rives of Grief,” is an instrumental opening with atmospheric tones and a horror vibe. The slow burn in the song’s first half is magnificent: creepy, dark, and evil. The tension builds up with a stalker’s lust, the instruments opening up more and more, each passing second adding another impossibly extreme layer. It takes a lot for instrumentals to get my attention and this one did, one of the best ones I’ve heard in months.
Mutagenic Host have released one hell of an album with “The Diseased Machine.” It’s rare that a debut hits like this but one listen is all that will be needed to understand how they pulled it out. Highly recommended.
