the records you just mentioned are recorded by Michael Keene, who is IN the faceless. Nothing majorly special about the recordings other than very separated instruments squashed to hell with a master buss limiter. Those records don't need dynamics, so it's just a lot of pump pump pump in your face with a combination of roboticly gridded material which lends a hand to transients working together instead of causing clutter, and subtractive EQ everywhere to make sure that certain elements aren't stomping on other more important elements. The guitars on the faceless record to sound pretty damn good, but i don't like the veil of maya mix. really blown out and kinda dull, lacking top end, and a little TOO sound replaced for my liking.
Anyways, your answer in short, programmed drums, good samples, DI guitar and Bass chopped and gridded to perfection, and compression compression compression
