Review by Sonny for Mental Devastation - The Delusional Mystery of the Self Part II (2025)

Despite my well-publicised obsession with chilean thrash metal and the fact that Mental Devastation have been around for well over a decade and a half, I haven't crossed swords with these guys before and so went into it with great anticipation. Now strictly technical thrash metal doesn't always appeal to me so much, as I like my thrash to have an inherent aggression and fire, that I think is often lost amongst excessive technicality. As is usually the case with chilean thrash, though, this certainly delivers on the passion and aggression front, whilst also displaying an impressive level of technical ability. The usual chilean hallmarks are all present, breakneck pacing, vicious vocals and pronounced basslines, all well-represented by a nice, clean production job.

Following a brief anticipatory intro the opener proper, "Symbiosis", tears out of the blocks with a riff that proceeds to tear any unprepared listener a new one. With exuberant, energetic guitar soloing and bassist Alejandro Lagos' aggressive vocal delivery this is proper celebratory and whiplash-inducing stuff. They are perfectly capable of dialling it back a little though with "Judge and Jury" initially hitting a more mid-paced tempo. It is at these lower speeds, however, that Lagos' limitations as a vocalist are exposed as he maintains the ragged delivery he uses on the blisteringly fast tracks, which doesn't really suit the mid-paced stuff at all well and feels a bit like a sonic splinter in the thumb of the album. They also attempt something a bit more progressive on "Pulsions" but the gentle opening section exposes the vocal shortcomings even more.

I don't think that the technical aspect of "The Delusional Mystery of the Self Part II" is especially pronounced, certainly as far as the songwriting goes as the riffs still rule the roost here. For my money, dual guitarists Matías Morales and Felipe Espinoza are the guys who provide the secret sauce. Their riffs are pretty good, but their soloing is the real draw for me, delivering a great line in short, sharp shocks without sapping the momentum from the tracks by becoming too self-indulgent, even during the track "Primitive Paths" where they really go to town. All-in-all this is a very enjoyable slab of chilean thrash with enough energy and aggression to keep pace with my favourites from that neck of the woods, but which is robbed of my highest marks by the vocal limitations which I occasionally found too jarring to excuse and the superfluous instrumental "Dõ" which, for me, had no place being here at all.
