Also called sludge

Kind of Doom metal

Late-1980s–90s Southern slow-and-ugly metal: doom weight plus hardcore bark (Eyehategod, Crowbar). It hears Doom metal for the riff and Hardcore punk for the shout and hall dirt. The Melvins stay a mediator, not a node. Later sludge-adjacent names stay on this node except the named Post-metal child.

Passed on

Post-metal style · 1996–

Post-metal takes sludge’s slow ugly riff and hardcore shout residue and stretches them into long dynamic forms.

Influence

Doom metal → Sludge metal

meter and groovetimbre and productionharmonystrength: highwell documented1988–1994recordingoral

Mechanism

Sludge keeps doom’s slow heavy riff and dirties the vocal and the room. Strength high. Hardcore hops wait on the sludge node.

Evidence

Eyehategod and Crowbar against 1980s doom; Grove on that fork.

Debate

Whether this is already hardcore. The riff parent is doom; the bark is the later hop.

Mechanism

Sludge keeps hardcore’s shout, feedback, and DIY hall and slows them onto a doom riff. Strength high. Doom supplies the weight (doom metal sludge metal); this file is the punk half. Do not mint a Melvins node — that band is a mediator, not a practice.

Evidence

Eyehategod and Crowbar 1990s sides against Southern hardcore; Azerrad on the U.S. hall circuit; Grove on the doom/hardcore meeting.

Debate

Whether this is already doom. The riff parent is doom; the bark and the dirt are hardcore’s.

Sludge metal → Post-metal

Mechanism

Post-metal takes sludge’s slow ugly riff and hardcore shout residue and stretches them into long dynamic forms. Strength high. Post-rock leftover as a neighboring crescendo name, not this parent.

Evidence

Neurosis Through Silver in Blood against New Orleans/Eyehategod sludge weight (Grove).

Debate

Whether this is already sludge. The short ugly club song is sludge’s; the named long-form art-metal job is post-metal’s.
