skimmed thru, here's what people posted so far that I'd put in the dissensus canon and, briefly, why
first, you have to decide what your criteria are. I'd rate how much it reflects the character of the place over quality, or my own personal tastes.
also, I'd weight it more heavily toward the early days, as the foundation predates the rest of building
given that:
Heavy Mental - craner's psychogeographical keystone/favorite record
The Infamous and/or Enter the 36 Chambers - luka, blackdown, the hardness of mid-90s jungle samples
PIL's first and/or Metal Box, Wire's first 2 - the foundational records of post-punk, which blissblogger wrote the book on
everything in Can's peak (Monster Movie thru Ege Bamyasi, tho some people would probably argue for future days) - spirit of woebot's top 100 etc
On the Corner - barty
Sign O' the Times - I think 1999 + Purple are both better, but probably the most dissensus Prince LP, plus the Kode9/Spaceape cover
Spirit of Eden/Laughing Stock - whence "post-rock"
The Prodigy - Experience; only important or good ardkore LP, so no-brainer
Aphex - personally I'd 1000% pick SAW 85-92 over II which I find dead boring but in honor of droid's 90s ambient techno DJ days it's gotta be II
