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
Especially for folk/Americana, acoustic fans,  I highly recommend checking out The sound track to Ken Burns' 'Lewis and Clark' series. This music will move you.
When I read the title of this thread the first album that immediately came to my mind was
"Blue Maqams" by Anouar Brahem. I discovered it last year.

It’s a fusion of jazz and Middle Eastern.

I always knew I was searching for this album without ever realizing that I was searching for an album that fused jazz and middle eastern.

If you’re picking up what I’m putting down...
Rufuge by Gabrielle Roth.  YouTube has parts of it.  Ancient Tibetan chants (not  mellow droning chants) sung by Russian rock singer.  Very powerful (and some nice bass).  Close your eyes, put it on and experience it.
