Suggest one obsure album we all should hear

Cheap Trick- first two 
ZZ Top- Fandango
Rory Gallagher- Calling card
Pat Travers Band- Go for what you know
Frank Marino- What’s Next
Ted Nugent- Free for all (meatloaf on vocals)

Since @1111art seems to have an appreciation of 70's prog, I will suggest:
 Nektar- A Tab In The Ocean

Not sure if that is obscure or not these days.  If you reside in a state where pot is legal, it will help.

Obscure Arizona group, similar to blood sweat and tears.& Chicago.........Eclectic Mouse..........( circa 1970??72)....you can find individual traks on youtube..............also "Barefoot Boy".... By Larry Coryell.........early fusion masterpiece!!!!......Shakti' s first lp as well.....

Ok....i forgot one.....Iva Bittova.....her first lp....I think it is either titled "Iva Bittova.."..or"  Strange Young Lady"........ Hauntingly beautiful!!!....meridith monk meets laurie anderson in transylvania!!!!..... Also shout out to the Batdorf and Rodney selection....saw them at U of Az in 1973.......

Sincerely-Dwight Twilley Band
Power Pop masterpiece, the album release was botched by Shelter Records, a hit single, I’m On Fire, was released.  The album was not released for another year, all momentum lost.  That’s why it’s obscure.
