A) It's such a definitionally open ended and experimentation friendly genre. I wouldn't be opposed to seeing BM split into 2-3 completely different genres. I still find rather difficult to rationalize some acts being "under the same roof" as others.
and
B) Lots of one man projects that work out surprisingly well
Thy Catafalque. The new album is so insane! This is the kind of shit that makes me want to blaze out of my mind and just lie in bed listening to it for hours. Such a gem of an album. I encourage everyone to check it out.
Adora Vivos is another ass kicking band I discovered this year.
Aburadako/あぶらだこ, Japanese noise rock/punk that gives me the same vibes I get from Foetus, a bit of swing and bombastic drumming. Vocalist sounds like a cartoon villain but I love it.
these are the best two things i've come across this year. the former is the best old-school DM i've heard in a long time - maybe top 10 ever level shit for me - the latter is the closest thing to arch-era fates warning i've ever heard.
