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
As requested by the OP, I will only list one even so I have at least a good dozen that would beat the pants off the likes of Fleetwood Mac Rumors and Steely Dan Aja as far as audiophile quality goes.
Kevin Ayers- Diamond jack and the queen of pain.

Check out the first song on the only album Solid Oak by Top Drawer. Wicked good! Rest of the album is so so.
