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
trentmemphis,

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.
Phil Manzanera’s (of Roxy Music fame) Primitive Guitars

Some names mentioned here I haven't heard for years. Root Boy Slim and Moondog to be sure. Impressive. 
Rhiannon Giddens- there is no other.
She has a fantastic voice, and this mix of songs will make you wonder where her heart lies.
Is she Natuve American? Is there some Irish Folk in there?
2 LP version is beautifully produced. Some of the quietest vinyl I own.
