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.
