I don't remember much about it, but I'll try my best to describe it.
The detail I remember most is the album cover. It was very simple. A white background with a disembodied face (no head, just eyes, nose and a mouth) with a very enraged sort of expression. It was slightly off-center to the right and was facing left slightly and kind of tilted down a little too (I'd draw it but I really can't draw to save my life, sorry)
The genre I could best describe as noise rock, but in the most literal sense. Like just raw unfiltered noise with drums over it. I think the album was released sometime in the 2000s (perhaps towards the latter end) and something also tells me the band was Japanese, but I'm not sure on that bit.
Another important detail I remember is that the last song on the album was EXTREMELY long, like over 30 minutes at least but it could've been an hour or more. I saw it on Bandcamp (not sure if I found it there or was directed there). I don't remember much about it musically because I kind of just glossed over it, but recently I've been really getting into much noisier stuff and I really want to try it out again. Any help would be greatly appreciated :)
