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'
128x1281111art
Steve Roach/Jorge Reyes - Vine Bark&Spore.
Tribal ambient music.

Vas- In The Garden Of Souls.
Rasa - Devotion
Female vocal.
Mudcrutch's first album, featuring Tom Petty pre-Heartbreakers.

Jimi Hendrix "Crash Landing" - different take on some of the songs you might be familiar with; no input from Hendrix or his band members and some extreme editing was undertaken to make the songs more "listenable" so don't mistake it for an actual Hendrix album.
Andrew Gold - The Fraternal Order of All
The Wondermints (Brian Wilson's backing band)

What a great thread. Where else would we find such gems as "Eight Hitchhiker Inscriptions..." by Harry Partch?  (the king of non-12TET)

Maybe I missed it, but I didn’t see any Fred Frith yet.

My pick:
Espers "S/T"
Harry Partch
San Diego State prof.  In particular Eight Hitchhiker Inscriptions from a Highway Railing at Barstow California
Tidal has it, album is  The World Harry Parch
He designed and built his own instruments and tonal scale

I thought that the McLaughlin Trio was CD as well. Thankfully, it was released in ’90 and reissued on 180g (German-Optimal) in 2015.

That album was a huge inspiration as I’m a bassist. Kai Eckhardt went from Berklee School of Music to landing this gig. Beautiful fretless and fretted playing. Trilok Gurtu, known as an Indian percussionist, plays trap kit, though I believe he was seated on the floor, IIRC.
MANNHEIM STEAMROLLER 
First eight "IN THE AIRE" ALBUMS.  Most can also be found as LP's

Also MANNHEIM STEAMROLLER CHRISTMAS ALBUMS - The first four releases. 

Absolutely ICONIC music. LIke nothing else that has come since. Great listening that a wide range of people all love. I own them all. 
Trio Live Oak- “Star Shining On The Mountain” This is early Spanish music. This is very calming and beautiful. The recording has a great sense of space as well.

New York Rock Ensemble- “Fields Of Joy” I have loved this song since my older brother brought this record home from college, maybe 1971 or 1972.
Ramsey Lewis Trio, 'Pot Luck,' 1963

Robin Lane & the Chartbusters, Eponymous, 1980 ("Don't Wait Til Tomorrow")

And ditto to 'Argus'
Also didn't see that jb1 had posted already for the John McLaughlin trio. Never heard it but can only ditto from inference.
Some amazing recordings suggested here. The Mahavishnu Orchestra - Apocalypse.
If you can find it John
McLaughlin Trio Live at the Royal Festival Hall: Cd only so Vinyl lovers are out of luck. Its on a small private label called JMT: Its been out of print for awhile but its worth the effort if you are into that form of experimental Jazz. The band fires on all cylinders on this one.
Fizzy, Fuzzy, Big & Buzzy-The Refreshments
It's oddly available on vinyl. 
Not sure why I like this album but it's got some magic to it. 

“Tricky” by Domenic Troiano, the whole of side two is absolutely brilliant. Recorded in 1972. 
Mix of new and released many years ago. Also, totally different genres from most mentioned and all have outstanding engineering...

Cinder Well - No Summer (folk)

Jonny Nash (minimalist pianist, mechanical drawer organ) with Suzanne Craft - A Heart So White (“Knife” is an incredible and quite unique cut on an excellent album); also check out his album Poe featuring Teguh Permana (member of Tarawangsawelas on Morphine Records) who specializes in the sacred Tarawangsa, a two-stringed instrument used in the sacred Tarawangsa music of Sunda, Indonesia. Both albums are quite beautiful.

Trifonic - Convergence (classic of classic electronic album made by the Trifon brothers. Every song is excellent and the engineering is exceptional (such as what I picture as a long chain that curls up and is extended across the soundstage and is pulled back like a whip several times). With the right room (golden ratio sound room my dad had built) in the cut “Infiltration”, while sitting in the "sweet spot" chair, at 1 min 47 sec a "whaaaaaaa" spinning buzz (which I picture as a spinning pin wheel that has been electrified) emanates distinctly and for a fairly long duration out of the rear wall behind me at 10 o'clock. I heard none of the related sound structure coming towards me just prior to this sonic event (just got a spine tingle thinking about it). I communicated with one of the brothers and he has no idea he had engineered this into the album and had no idea how it occurred (I assume there was a sonic cancelling occurring that then released at just the right moment). Only my dad’s (now mine, soon to be totally updated with Graz Parts by Music Technology in Sterling, VA) Apogee Duetta II Signature Series full range ribbon speakers have been able so far to reproduce this incredible experience. Go figure.

I could list pages of albums that will qualify as obscure to most that are outstanding, but I’ll leave you with these 4 albums.

Neutral Milk Hotel, The Airplane over the Sea

Slint, Spiderland (if you like the Pixies or Nirvana in particular, you'll definitely like these guys)

Meth Teeth, Everything Went Wrong (Oregon, indie music, yes, that's the name of the band and yes, that's the name of the album)

for those into heavier music, check out Thou, sludge rockers from Baton Rouge, either Summit or Heathen is probably their best, for an intro, check out Rhea Sylvia, their tribute EP to Alice in Chains

also, for fans of harder music, check out Steel Nation (Pennsylvania hard core band), The Harder They Fall

if you're into something really odd but interesting (odder than Meth Teeth musically), check out Gar Gar, a band from Louisiana now in Oregon


Mike Moreno, Between the Lines

Eyolf Dale, Return to Mind

Both great modern jazz recordings, great performers, and both stunning, and tonality beautiful studio captures of evocative and nuanced interactions of these great musicians.


Mercury Rev - See You on the Other Side Fantastic 90s psychedelic indie rock record, produced by one of the members of the Flaming Lips. Incredible record and a great recording, especially on vinyl.

June - I Am Beautiful If you like Throwing Muses or Pixies, this is a 4AD band from the 90s that never caught on. Great record, also a great pressing if you can find it on vinyl.

Prick - Prick
Produced by Trent Reznor, one of his music heroes from the Cleveland industrial scene.
The first 10 songs on Let's Active's 1986's "Big Plans For Everybody" is pretty much can't miss.
Nice calls all around. Yup,  Argus's "The King Will Come" is a fun song that has a very catchy hook.  And Chris Squire's "Fish Out Of Water" is a borderline masterpiece, especially if you like incredible and melodic bass.
John Konjos “John Konjos”
Sandy Denny “Like an Old Fashioned Waltz”
Faces “Long Player”
Amazing Rhythm Aces “To Stuffed to Jump” 

Glad to see so much recognition of Pink Martini! Great band!

Ok, let’s try again, shall we?

The Grapes of Wrath - All the Things I Wasn’t
https://www.youtube.com/watch?v=vy6sNR9CYrU
Looks like Kevin Ayers is getting quite a bit of love. 
Try Deia vu if you can find it, another sublime album by him, music and incredible sound.
Dave Brubeck with Tony Bennett live at the Whitehouse 1963 for JFK. YOU ARE THERE,,SERIOUSLY!

Valium Aggelein - Black Moon
Mostly instrumental spacy Krautrock
It's a compilation reissue of some rare releases from the 90s from the alter ego of the band Duster
Geraldine Fibbers. Lost Somewhere Between the Earth and My Home

Cowboy Junkies. Whites Off Earth Now.
