Maybe Kenny Burrell? It seems there are some odds and ends that are trickier to find. Something of an interesting catalog - the first two kind of stand together, then the two jam sessions, the live album, Midnight Blue and the odds/ends. I might be a buyer, I love his tone and most of those albums have grown on me over the years.
Maybe a collection of "one album" Blue Note artists, although I am too lazy to compile a roster. Probably a little gimmicky for the Mosaic folks.
Those Selects filled so many gaps!
