What are the "Must have" LP's?

Black Uhuru - The Dub Factor

One can never tell if you will like the music, but this WILL show off a systems capabilities, more vigorously than any other that I am aware of. A must have for me.

If I may, I'll add a few of my favorites:

180g Reissue from Acoustic Sounds:
Sonny Rollins - Saxophone Colossus
Bill Evans Trio - Sunday at the Village Vangard
Creedence Clearwater Revival - Any of the reissues

Reference Recordings (45 rpm) Out of print, but available used
Mickey Hart, Airto, Flora Purim, et al - Dafos
Respegi/Pacific Symphony - Church Windows

Classic Records (RCA reissue)
Mussorgsky/Reiner/CSO - Pictures at an Exhibition

United Artists
Nitty Gritty Dirt Band - Dirt Silver and Gold (3 LP set, out of print, but I just picked up a very nice used one here on the 'Gon) Well worth tracking this down.

The Doors were really well recorded, and good for showing off the ol' system.
