I'm not a specialist but after a few research it seems safe to say that "Pulse X" is one of the mother releases of grime, that pulsating and brutal, typically londoner genre which contributed giving birth to dubstep and bass music in the early 00's. So what do we have here? Pure, raw, strictly underground beats & bass, totally urban yet absolutely animal - the super minimalistic, direct, obvious yet alienesque way of the ingredients and arrangements could evoke something like a grime equivalent to LFO's "LFO". One can assume that this unrefined, super sharp vibe did spread all around the world as you hear hints of the brazilian or south-african underground electro scenes in this monster, seminal tune.I discovered and ID'd this courtesy of the ever precious Ben UFO, who went record digging in some private warehouse with FACTmag, and was checking a version of this tune on his portable vinyl deck in front of the camera. Hope he picked it up finally!
