Reddit reviews Devil Seed

Don't worry about it, just a downvote. Probably someone who doesn't like non-music content on this sub. Anyway. I looked around and you weren't kidding when you said "one of the most unknown ones too". One of the commenters in "RAY-NA" said "このアルバムをあちこちで探しているけど見つからない。", "I've looked for this album everywhere, but I just can't find it."

I could barely find anything but I'll just give you what I got. Wolf on Japanese Amazon. The digital music section is much more extensive than the physical purchases (23 pages), but I have no idea if you can buy digitally from Japanese amazon in North America, I only have experience with physical purchases.

Whether the stuff on amazon is actually their music or not, I was too lazy to check, sorry.

Outside of that, I also found another one of their albums not labelled properly under the author name, so it wasn't included. Their may be more of these if you search the word "wolf" under the "CDs and vinyl" section".

edit: I just found another artist listed that seems to be the same band here.

Less important is this fan website about them. It gives some info, and I can try translating it if you want, but I doubt it would be giving you much help apart from knowing who is who in that group picture.

edit: oh and I found another fan website, but it implies they only ever released one "full album", which I find odd. Maybe the stuff on amazon isn't even them, or maybe this guy is talking nonsense.

I found yet another fan site after but I'm guessing you're sick of them. One thing noteworthy was said in it though, saying that one of the band members said "if Matsumoto won't be singing there's no reason to do this band" upon breaking up.

Anyway I've got a headache so I'm gonna leave it at that. Hope it helped.

edit: and btw I say "fan site" but it's more just single posts on blogs by people interested in that kind of stuff.
