In early 2019, Gridfailure released the album Sixth Mass-Extinction Skulduggery I on the American label Nefarious Industries. This album is the first in the planned series of albums under the general title "Sixth Mass-Extinction Skulduggery". It is planned to release five albums in total. This first part is released in digital form, but it is planned to release physical media. You can listen to the album and place an order on the label's website, as well as on the project’s Bandcamp page.

The cover is a monochrome black and white drawing in pencil, ink or felt-tip pen. On a white background, in a rather infantile manner, many human skulls are drawn, folding into something resembling tentacles. Several skulls impaled on stakes. At the bottom of the image on the highlighted white field is the black Gridfailure logo, which is a fairly simple solid font, slightly distorted by some semblance of rust or dirt. Slightly above, in small black typewritten type, the name of the album is written - "Sixth Mass-Extinction Skulduggery I". In general, the cover seemed to me very simple and a little dirty, but quite interesting and not without some appeal, but it would be more suitable for the work of some Death Metal or Hardcore band.

The album, with a total duration of just under fifty-two and a half minutes, consists of eight tracks of different lengths. The shortest track is called "Dysmorphia For One's Neighbor" and lasts just over one and a half minutes. The longest track is "Directly In Its Path", lasting more than 17 minutes. The musical part of the album is quite original and interesting, which is difficult to adequately and accurately describe. I would call it Dark Avantgarde Drone Industrial with Death Industrial influences. But this is a very free and approximate formulation. On the album we have a very dark and oppressive, almost claustrophobic atmosphere, despite the rather surround sound. It is a blurred sound cacophony consisting of harmonious and disharmonious parts of acoustic and electric musical instruments, as well as field recordings, vocals and effects. All these sounds are mixed so much that it is sometimes difficult to pick out any particular instrument. However, vocals and field recordings are brought to the foreground. Despite the apparent chaos, tracks can be traced compositionally. First of all, it is backed up by minimalist percussion elements, which are mostly single blows at a certain interval. However, sometimes, the drum parts become more ritual. In some moments, there is a clear impact of Death Industrial - we can hear distorted, buzzing monotone synthesizers. The vocals of Dave Brenner are almost Death Metal growling, distorted by effects, in the spirit of Death Industrial and Power electronics. While listening to the album, I found myself thinking that Gridfailure is a crazy mix of Natural Snow Buildings, Pocahaunted, Brighter Death Now and various psychedelic sound experiments.

It should be said that Dave Brenner invited a number of musicians to record, so the list of musical instruments used to record the album is quite large - Electric Drums / Percussion, Theremin, Accordion, Bass, Ukulele, Violin, Harmonica, Keyboards, Acoustic Guitars, Xylophone, Analog Synth. I may not have listed all the tools.

Some time ago, I was reviewing a Gridfailure & Megalophobe joint album called Tasukete, from 2018 on the same label - Nefarious Industries. My acquaintance with Gridfailure began from this album. The joint album turned out very uneven and overloaded with various elements. At that time I thought that if Gridfailure & Megalophobe had released their musical parts separately, it would have sounded much better. And it seems to me that I was right. The solo album of Gridfailure made a more favourable impression on me. However, some parts of the compositions seemed a bit boring to me. Also, with all the rich tools, the album is somewhat blurred and raw sound. I would like to hear more sound purity in order to clearly hear at least some of the musical instruments. In general, the album turned out pretty strong and solid. All compositions are made in the same style and have the same atmosphere. I can't call Sixth Mass-Extinction Skulduggery I a masterpiece, however,  I think I’ll it a  few more plays
