Suggest one obsure album we all should hear

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.

Jesse Winchester. Just about any of his albums, but, to name one, his self titled 1st. 

The track “Kucano Oro” on the MA Records release The Old Country.  Features otherworldly harmonica from Howard Levy and superb percussion by Mark Nauseff, with reference SQ. The track “Kit Carson” by Bruce Cockburn on Nothing But A Burning Light. Spookily great in every way if you can handle the message.
