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
Obscure, you say?
Here's a good intro to Harry Partch, a brilliant iconoclastic composer who designed and built his own instruments and employs a microtonic (43-tone) scale:

Music of Harry Partch, Vol. 3: Sonata Dementia 
or
The Harry Partch Collection, Vols. 1-5
by Gate 5 Ensemble
