Suggest one obsure album we all should hear

First one to come to mind:

Diga Rhythm Band

a sonic treat.

Roy Orbison - In Dreams : the greatest hits (1987)

It's not obscure but I don't see this record mentioned anywhere close to enough as to what I feel it should be.

In my experience this is one example where digital and analogue virtually coincide.

If there is a better sounding Roy Orbison album out there, then I haven't heard it.

Bryan Ferry "Boys and Girls": All star lineup. Used to play this on a long trip when we needed to go that last hour.

Kraftwerk: 3-D Catalogue. Reworked old favorites. Amazing sonics.

King Krimson Live in Montreal: Especially "Sartori in Tangier". Tony Levin bass line alone is enough. Throw in Fripp and Belew. Epic
Gong: Shamal. Mid 70’s space jazz. Steve Hillage guitar!
System 7: Their best album is out of print and not even on Amazon. Listen to what you can. Guitar synthesizer and deep house(I think).

Weather Report Black Market: Jazz fusion. Jaco Pastorius on bass.

Dallas Wind Symphony, Frederick Fennell:  Trittico.  Great orchestra with stunning sonics. 

That’s all I used to buy was "not commercial" so let me know if you want more. LOL

The first (self-titled} Seatrain album. Still love it.

obscure may be the wrong word, it is a new album from a new artist

matt carmichael - where will the river flow

beautiful lyrical jazz, great sound quality

in addition to the absolutely lovely music, it is an excellent test of truth of timbre of a hifi rig
