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'
1111art
For those who enjoy post-punk, the following albums are from a band called 'The Sound':

Jeopardy

From the Lion's Mouth

Not sure why they didn't achieve greater fame, but the music remains. I discovered them several years ago. Hope you find them enjoyable as I have.
For the Zappa and Beefheart fans, there is an instrumental version of Willie the Pimp from the Hot Rat Sessions (a demo?)  that I really enjoy.
@Denezy52 I agree with Captain Beyond, although I think Sufficiently Breathless is a superior album, personally. Also:
Atomic Rooster - Death Walks Behind You 
Audience - House On the Hill 
Illusion - Out of the Mist (original members of Renaissance)
