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
" Pink Martini - Splendor in the Grass"

My nephew is the tour manager of Pink Martini, Thomas & the crew.
God, I'm having fun listening to (and buying some of) these suggestions!
Thanks guys.
Here's a group/album that is my favorite (makes you feel good-like the person you know you could be) album.
Midlake     The Trials of Van Occupanther
