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'
63034d6b 96ca 4678 9ab3 3f915e0a1b021111art
There’s a lot mentioned here that I don’t consider obscure at all, so maybe my 2 also aren’t obscure. But, here you go:

Philip Catherine “Nairam”
Beaver and Krause “All Good Men”
Esthero - Breath From Another
Digital at Montreaux Album
Features Dizzy Gilespie, Toots Theilman and Benard "Pretty" Purdey. Live.
Also anything Frank Zappa.
What’s more obscure than a Mendocino beano or a Camarillo brillo? Not to mention a Jewish princess with a garlic aroma that could level Tacoma.
Zappa fans know what I’m talking about!
I’m sorry to list more than one but I could not stop. Did all I could to stop here. These are musically and sonically great albums. Strawbs Hero and Heroin
Warren Zevon Warren Zevon 
BeBop Deluxe Sunburst finish
Camel Moonmadness
10CC Bloody Tourst
Crack the sky Animal Notes
Wishbone Ash. There’s the rub. 
I am stepping away from this post. 

Yea, forget the 'post just one', have at it!
Here's another 'Baxter'. Moody, jazzy, smokey voice.
Just Cool......
