Husker Du "Warehouse: Songs & Stories" -- somewhat derided as overlong and pretentious, but I think it almost stands alone as a "mature punk rock" album (i.e., not doing songs "for the kids" anymore). Something like 25 tunes on there, and lots of them are real gems. Only drawback for me is the dreaded "80's gated snare".
Replacements "Hootenanny" -- all the hype was due to the albums that followed, but I think this is a pretty hilarious bunch o' shit! Almost like Jon Wayne's "Texas Funeral" in outrageous badness.
Rolling Stones "Their Satanic Majesties Request" -- I think it's their best album!!!
