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'
Any Sheffield DIRECT-TO-DISC album will open up your eyes and reveal the positives and negatives of your system IN YOUR ROOM.

Try it and see--it is remotely possible you might learn something!

This Mortal Coil --Filigree& Shadow--Never knew I had this Gem was using when I just grabbed anything out of my 2k LP collection to check out a new Cartridge This Album is Killer for Sonics.
There's a couple mentioned so far that I'm going to check out. 

Small Faces' Ogden's Nut Gone Flake is  an album that I've often seen mentioned but the lack of a single probably resulted in it not getting much radio play.

The other is the Moody Blues In Search of the Lost Chord by the Moody Blues. It's a little wordy and metaphysical but sometimes that's not a bad thing.

I gave Van Dyne Park's Song Cycles a quick listen earlier, it's got great sonics but that voice was a bit of a struggle.

Anyway, Richard Hawley's Truelove's Gutter is my favourite album of his. Very playable with nothing there that makes me want to skip tracks.

Here's the relaxingly hypnotic Remorse Code off the album with an odd video.
