I would love it if you would make a kind of "freedom jazz" list ! Your ratings/ recommendations for this genre are really excellent ! I know that there are many of these albums on your phantastic "soaring vocal jazz"-list, but its not exactly the same.
Hey, I think you should check out Coin Coin Chapter One: Gens de couleur libres. It's very freedom, afrocentric, free jazz with poetry in the vein of lots of the stuff you love (none of that slick modern production).
+ nice disco ratings
I like your album-art list, since it focuses on Vinyl.
I made a similar one as your, though not that well-maintained.
Have a peek sometime. I probably use some of your suggestions on your list eventually to "complete" mine.
