STAB Electronics "Day Of The Male" is pure heavy electronics satisfaction, indeed. I've heard a couple of Scatmother pieces on YouTube and they sound pretty okay to me in that format, so might be interested in this album.
The title track of Merzbow's "Psychorazor" is classic Merzbow in the full sense - all the swirling, jagged synth sounds and hard, harsh, constant forward motion, tension and release blurred together as with all the best Harsh Noise, a fucking brilliant reminder of how good Akita can get. The rest, though, left me underwhelmed, probably because it came after such a classic piece. More rhythm fucking, good on it's own but doesn't show up well compared to better material.
Right now listening to Third Organ's "The Pornography Of Despair" (a title I wish I'd thought of). Satisfactory stuff, fundamental cassette-era Harsh Noise, jagged but not too fast and spikey, lots of nice emphasis on screeching feedback at all tones and levels.
