Industrial Music

boyd rice & frank tovey - Easy Listening For The Hard Of Hearing is a current favourite. parts sound like a primitive porter ricks, other parts sound like looped field recordings of factory ambience, but it's really deep listening stuff and not as noisy or abrasive as you'd expect.

This'll be great:

Treblezine put together an article and Spotify playlist:

Not all of it is specifically "industrial music" per se, but that's not the point:

What we have in the end is an attempt to tell a story from the earliest experimental musique concrète and cacophonous psych acts on up to the terror pulse of the present day. These are industrial music’s roots, inspirations, landmarks, triumphs and the songs upon which its influence has been imprinted. Follow us on our dizzying descent.

I think they do a pretty good job of that and the Spotify list is a lot of fun to listen to in chronological order.

RIP Monte Cazazza, all time hero and inventor of the term 'Industrial Music'.
