I'd put them more in the proto-noise rock post-hardcore lineage - No Trend, Scratch Acid, etcCould Laughing Hyena's count here?
there's a crushing, trying to overwhelm, intense aspect to some techno as well i think. there's degrees of heaviness in techno for sure. although you're right, it still is trying to get people to move. it's not the point of it, it's just a part of the point.
quite a fair bit of 70s hard rock bizness still sounds heavy as a ton of bricksits why sabbath is still pretty heavy despite sounding tame comparatively to all its successors
The DJ Screw thing's another form of heaviness, slowing stuff to a crawl.
What I think is interesting about the heavy is how immediate it is; immediate in the same way the emotional impact of a pop song is but typically left out of pop music. I think the bassline of this kate bush song is traditionally heavy but I cant think of many examples
good call on chopped and screwed. that fits the thing we're circling around. rabit's stuff has the same kind of thing.
amapiano kind of has that sluggishness and heaviness i think, not exactly to the same extent as electric wizard but certainly that's one of the things that sets it apart from other things in the same spaceI guess the heaviness that comes with dropping the tempo is to do with what Linebaugh's saying about movement, restricted or sluggish movement implying some sort of weight acting upon it.
