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'

Here’s something I’ve been listening to lately. Not an album per se but the band.....

Patience is duly rewarded!

Oh and +1 to those who mentioned Angel. I think I wore out their debut album on my turntable back then. Thanks for all the great suggestions!

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.
