Putrefacao Humana - Colhendo Desespero 7"
Cult Brazilian brutality here from 1994. I've heard this described as "noisecore" - and these guys came from the same starting point as the seminal Brazil noisecore bands - but even by the pretty rough standards of those bands, this is out there. No noticeable differentiation between "songs", no drums audible, just an absolute barrage of high-end screeching guitar feedback, unrelentingly savage noise.
