This UK label is re-issuing some very fine music at the moment; both jazz and soul/funk obscurities. Full details here:

I recently bought a number of their compilations - "Spiritual Jazz Vols 1-3" & "The Best of Jef Gilson" and they really are a treasure trove of hard-to-find music.
I've no idea whether the Jef Gilson contains his "best" but there's some seriously good music in the compilation. The highlight is probably his version of Pharoah Sander's "The Creator Has a Master Plan", recorded in Madagascar in 1969 with local jazz artists. Before this release the only thing I knew about him was that he used to own the French jazz label "Palm Records", which recorded and released a number of terrific albums by US artists visiting France in the 1970s. Byard Lancaster, Frank Lowe and Khan Jamal all had some of their earliest recordings released on Palm. I understand that Jazzman Records are currently delving into the Jef Gilson archive, so hopefully some of those records might see the light of day in the future.
As well as the compilations they have also released a couple of other jazz obscurities - "Ohio Penitentiary 511 Jazz Ensemble - Hard Luck Soul" & "Bobby Jackson - The Cafe- Extraordinaire Story", neither of which I'd heard of before I bought them. They are both well worth seeking out.
