Les Amazones de Guinee: Au Couer de Paris (Editions Enimas Conakry)
Fine music, supposedly recorded at a live concert, but the audience sounds dubbed in, at least to my ears.
I'm not a big Billy Crystal fan and I don't know how much of a jazz afficianado he is, but it sounds as if he had some great connections with jazz musicians that are outside of my experience and he's been willing to share them.
Sounds like you're interested in semi-composed chamber jazz - kind of limited territory. I think that most jazz musicians who recorded with drummerless groups and most listeners to those groups (including myself) are are more interested in the improvising side of things. I guess you can throw out my recommendations. I didn't understand what you were looking for.
