Where do you start with Jade Warrior - they've quite a few LPs. In fact I looked at a recent vinyl reissue only today. What LPs do you particularly rate for the other bands you listed?
Honestly with Jade Warrior I'm pretty much mainly interested in their early/vocal stuff...the three LP's on Vertigo are all good and I'd rate "Last Autumn's Dream" best with the s/t close behind. I also listen to both of those far more frequently than the July LP...There's two archival releases "Eclipse" and "Fifth Element" that are pretty good too. I haven't heard the recent "Now" album that gets favorable reviews-it's got Glyn Havard on vocals again, who got they boot when they signed to Island with Steve Winwood's backing and went in a more new age/all instrumental style. The 4 Island LPs are all decent, but my attention kind of wanes and I think they're still worth picking up if they're cheap. "Way of the Sun" is probably my favorite of those.
Twenty Sixty-Six-"Reflections"
Captain Beyond-s/t ("Sufficiently Breathless" is okay, but kinda acoustic/Latin influenced and pales to the interstellar tapestry of the first LP)
Beggar's Opera-s/t, "Waters Of Change," and then lesser priority to "Pathfinder" (first is super energetic, organ-driven, and classical ripoff awesomeness, second is more subdued and has a ton of mellotron, third is kinda McCartney-ish in places and has a hilarious prog cover of "McArthur Park." Later LP's sound like an entirely different band due to personnel)
Traffic Sound-s/t (aka the "pink album" or "Tibet's Suzettes"), followed by "Virgin" and "Lux" (last of the three is kind of rough sound)
Far East Family Band-"Parallel World"
Eloy-"Ocean" and "Silent Cries and Mighty Echoes" and to a lesser degree earlier albums "Inside" and "Floating"
AB Kingdom Come-"Galactic Zoo Dossier" is pretty frightening in spots and truly fulfills the promise of the Crazy World stuff, imho. "Journey" is awesome too, but heavy on a 70's drum machine that give it a cool vibe.
Oh yeah, both LP's by Gracious! are awesome too for heavy symphonic prog with lots of mellotron.
