Mayhem "Esoteric Warfare" Cassette Asia version

Not for one moment does this album consider to give you any rest. It's a non-stop wall of furious guitars ripping through the insane and unstable drumming, mixed over Attila Csihar's quite literally guttural vocals.
Opening with a sanity-ceasing track, 'Watchers', it proceeds and progresses into crazier sounds of the songs 'PsyWar' and 'Posthuman', leaving you lost in the said 'wall of sound'. The guitars are technical in terms of black metal with chords scattered around the place, creating dissonance and an evil atmosphere suitable for the genre and the band's original sound.
Atilla's vocals are worrying. Any second you feel like his lungs will burst in the middle of a song for the amount of effort he puts into them is horrific, exploring random techniques to create the most odd and eerie, yet original sound, and is one of the things that really makes this album this memorable. Another feature of this record that doesn't make it too easy to forget is some of the most insane drumming you will ever hear on a black metal record. Hellhammer's double kick is restless. Ripping in batch series or even constantly maintained for minutes, it's guaranteed that it will be one of the first things you'll pick up on in this album.
It surprises me how Mayhem manage to re-invent themselves within each record, yet remain close to their roots in one way or another. They re-invent themselves image-wise and music-wise and so far, other than 'Chimera', this is their best attempt at taking a risk by stepping in a different direction as a whole. This is a record you don't want to miss out on if you're looking into the more gimmick-ridden, extremely aggressive parts of black metal or even if you're simply looking into the genre itself.
