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'
+ 2 BOBDG2000

Anyone who cares a whit about Steely Dan owes it to themselves to hear Root Boy Slim & His Sex Change Band....demented, freak-frat lyrics backed by a pro-level band.
e.g...from "He's Not Too Old For You"

Those lonely lonely nights that I keep adding to
30, 31, 32
The years come the years go
But I know I know
I'm not too old for you...
(backed by honey sweet female backing vocalists cooing "He's not too old for you...")

Not remotely PC....will offend all sensible people....
I like that album too. I would also add to this list White's "Transnormal Skiperoo."

Have you seen the terrific music documentary he made called "Searching for the Wrong-Eyed Jesus"? This look into Southern culture and music is very interesting. Among the musical groups featured is Sixteen Horsepower; I would include there album "Low Estate" on this list as well.

I like Transnormal, too, as well as No Such Place.  But Substrate is magical for me.  I can still remember the first time I listened to the cd, sitting in the parking lot at work in my Honda Accord.  I was immediately, totally absorbed by it.

I've listened to Searching, but haven't seen the film.  I'll give Sixteen Horsepower a listen, thanks.
I listen to Argus by Wishbone Ash fairly often...good stuff! Another album from that general time period that deserves a listen is Peaceful World by the Rascals (I know....the RASCALS???). It is almost a concept album and does induce peaceful feelings like the title implies.
Storyville - A Piece of Your Soul

This band is from Austin and features the rhythm section from the late Stevie Ray Vaughan along with 2 FANTASTIC guitarists and a black albino Vocalist who's voice is superb. I first saw them on Austin City Limits. They have 3 albums  which are all very good IMO. Hard to say which is best.
