Jim, I think #7 is an older recording (mid-late 60s) based on the recording sound - the studio sound, the mix, and the piano sound. It REALLY sounds like an Atlantic recording to me, but I find nothing in the Atlantic catalog that scream out "HERE I AM!!!", so I don't know. But that piano sound screams "ATLANTIC" (or Vortex or Embryo) to me, so I don't know. Once you get into non-American studio and label sounds, I'm pretty much lost, save for Tonstudio Bauer & ECM. And I could maybe, MAYBE, pick out a BS/SN label/studio sound on an artist I didn't know. Maybe. And besides, once stuff gets digitally remastered, you're often left with residual studio/label sound anyway, not the full deal.
Kenyatta (born in Martinique, I believe) has this same type of lush, rhapsodic alto tone, as well as this kind of faciltiy and melodic sense. His Vortex album on Atlantic would be a logical choice, except that I have it, and this ain't on it. Maybe he did a sideman date that slipped under my radar, but I don't think so. I WANT to pick either him or Sonny Fortune (and Leo Wright still, maybe), but there's not the discographical evidence to support doing so.
Ward I know only through the odd sideman appearance. He's recorded quite a bit with Ibrahim, but Ibrahim is one of those artists of whom I like virtually everything I've heard, but just haven't explored in any kind of depth. No good reason for that either, jsut haven't gone there yet.
How about Dudu Pukwana? Now there's somebody I've NEVER heard. If this is him, then that's my loss! His reputation is not of being this type of player, but since I've never heard him, reputation don't mean squat to me.
