While I'm hesitant to call anything perfect (besides Mozart's Requiem in D Minor maybe), these come pretty damn close:
Can - Tago Mago (greatest album in the history of popular music? I think so, and I've thought so since I was 16)
Pharoah Sanders - Karma
My Bloody Valentine - Loveless
Public Image Ltd. - Metal Box
Tim Buckley - Starsailor
Van Morrison - Astral Weeks
Swans - Swans Are Dead (a live album, mainly the best tracks from Great Annihilator, Soundtracks from the Blind, a few from Gira and Jarboe's solo albums, and a few originals. And it it is brilliant. All 2.5 hours)
Glenn Branca - The Ascension
Gang of Four - Entertainment
Miles Davis - A Silent Way
The End of Evangelion OST (it being paired with my personal favorite film of all time might have something do with this one)
