Defektro's label & company, Lastgasp Art Laboratories, has not yet been mentioned. He's been selling his homemade electronics out of Sydney for a good long while now. There's a huge Defektro discography to wade through, and I am by no means done. Originating in Japan, his focus for at least the last 2 decades has been on producing a machinistic version of noise. One could name something such as Vivenza as a starting point for this sort of approach.
-The only release I physically own is the Hard Luck Heart 7". It goes for almost offensively cheap prices nowadays, despite a limited pressing of only 200 copies over a decade ago - but I will treasure my copy all the same. I might buy up all spare copies on the market and hoard them for ever... Beyond the excellent tracks (Industrial March / Survive / Sakura / Hard Luck Heart) there's some unintended eccentricities that really make it quite priceless... Logo is stylized as "Defektro Noise Army" (sign me up!) and there's a motorbike picture on the centre label, like some hooligan antisocial bōsōzoku bootboy.
-At the top of my most-wanted list is his first tape "Noise Bomb" from '98 (released in JPN.), with a J-card cover resembling a time bomb, track titles such as Sine Attack / Percussion Cap / Sabulite, and a cassette with a built-in flash LED, with a switch in the case to turn on the light. Clearly a faithful adherent to the original idea of industrial noise as warfare. One of the greats!
Some other favourite tracks:
-"Euthanasia" on Steinklang Ind. "Japanoise of Death" V/A compilation. Loop-based.
-"Tone Climber" on the Sklo/Slovak split. Self-explanatory.
-"Pressure Gauge" on the Fear Konstruktor split tape.
