Miami bass comes to mind. Miami (probably my favorite city) is totally 4th world, and bass fulfills hard, rhythmic, machinic, not really psychedelic.
for sure hard machine funk for brown people tho - witness its diaspora to global bass musics generally + specifically its huge popularity in Brazil
specifically the harder ca. 86 + beyond Amos Larkin sound (as opposed to the earlier Pretty Tony Miami electro proto-bass template)
this is one of the first true bass records, Larkins
a little later once it's started speeding up, disembodied/distorted voice a bit reminiscent of the darker Chicago acid records
