Suggest one obsure album we all should hear

The Persian Santur - Nasser Rastegar Nejad. 

William Topley... prolific during the late 90's and early 2000's and is still at it today. Much of his catalog is available on Tidal and the recording quality for most of his material is quite good. Some samples from different albums:

@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)

Tony C & the Truth, DEMONOPHONIC BLUES
Ron Wood, GIMME SOME NECK

Captain Lockheed and the Starfighters 
Space Rock at its best
