Suggest one obsure album we all should hear


I love when I discover an album that's new to me, and great.Please share one so we can all broaden our musical horizons.

Mine is:
Wishbone Ash  'Argus'
128x1281111art
Da Da - Puzzle.

Not so obscure, I am sure most have heard the track Disknee Land, but it surprised me how well it is recorded and how musical it is.
Love this thread. I see more than my share of stuff here that is actually in my collection. And oddball names from out of my record store past and stuff I remember from ancient issues of Stereo Review.  A dive into deep nerd-dom.
Thanks again everyone. I've spent over $300 so far on your suggestions!And my first hi end speakers are arriving in a week or so!
Keep 'em coming...
