The new names mentioned on topic are great. Some "obvious" are not mentioned.
The New Blockaders Simphonie in X Major - for example. You could name debut album as classic, but this one has way more detailed nuance and neat tape saturation. Live at Anti-fest mCD, or 12", and now finally reissued by OEC as part of Morden Tower live CD, that is some massively great LOUD TNB. Not sure if it can be heard online, but CD is definitely must-have for metal junk/feedback lovers.

Debut Hanatarashi LP, not only good funny titles, but as a metal-harsh-junk album, early masterpiece that still today doesn't sound "old", despite it may not be as LOUD and crunchy as some contemporary noise. One could put POWER COCK playing anytime and mistaken it's the latest hot noise tape, but no. This harsh attack comes from mid 80's!
