There’s a particular sound that makes old-school death metal fans stop what they’re doing: a Boss HM-2 pedal with every knob turned all the way up. It’s the chainsaw buzz of classic Swedish death metal, and in the right hands it sounds less like distortion than like weather. HETEROPSY, a quartet from Tokyo formed in 2020, have made that sound the foundation of something sadder and stranger.
Mourning Death Metal
The band’s own term for what it plays is mourning death metal: death-doom built on the HM-2 roar, slowed down far enough to let grief seep into it. Two of the members also play in Frostvore, which handles straight Swedish-style death metal. HETEROPSY is where the same players go when the music needs to sink rather than charge.
The reference points they give are telling. Dismember and Autopsy for the old-school rot. Finland’s Rippikoulu, one of the great cult names of funeral-paced death-doom. Switzerland’s Sadness. Sweden’s Naglfar. Put those together and you get a band that is death metal first and foremost, but with what reviewers abroad have described as a vague madness and sadness running under it — a melancholy that never tips into gothic prettiness, because the guitar tone won’t allow it.
The Road to Embalming
HETEROPSY built its catalogue the way underground death metal bands always have: four EPs and a split before a full-length. The debut album, Embalming, arrived on 31 October 2025 through Caligari Records — a label with real standing in the international underground — and the premiere of “Memento Mori” through the US death metal blog No Clean Singing put the band in front of exactly the audience that lives for this sound.
Look at how that happened. HETEROPSY reached the global death metal underground through the channels that community actually uses — a specialist label, a specialist blog, Bandcamp — rather than through any Japanese media push. For an extreme band from Japan, that direct line to the international underground is often the fastest road there is.
Where to Start
Go straight to Embalming. Play it loud enough that the HM-2 fills the room, and let the tempos drag you down rather than waiting for them to speed up. This is death metal for mourning, and it does exactly what it says.
