Einsturzende Neubauten - Zeichnungen des Patienten O. T. (1983)
The roots of industrial music are weird. Very weird.
Scraping Foetus off the Wheel - Nail (1985)
More industrial roots, albeit significantly more accessible.
Glenn Branca - The Ascension (1981)
Sweet avant-garde album.
Comus - First Utterance (1971)
I should have listened to this ages ago.
