Suggest one obsure album we all should hear

Fleet Foxes self-titled Fleet Foxes

and a desert island fave for me that is obscure to many 
  - Dave Grisman Quintet 80

'Episode' by Avo Demirdjian, electric violin+band

Here is some prog rock from 2016. Start with the 3rd track, when the album really starts to take off. Here's that track at YouTube -- as good as it is here, it truly shines in hi-rez.
Trust me on that. I mastered the album.

Knopfler -  Good On You Son

Mainstream, but awesome. 
Great textures and groove throughout song and actually the whole album.

Donovan - A gift from a flower to a garden. One side electric and the other side acoustic. The acoustic side beautifully ethereal.

Tom Robinson Band,  "Power in the Darkness"   1960's Brit Rock that still sounds good.

Olu Dara,  "In the World" a surprise pick by Stereophile  Magazine as the album of the month some twenty years ago.
