"Little known" is pretty subjective... you mean, to the general public? To most Jazz fans? To most audiophiles? How are you defining this?
@wharfy
If the Counce release qualifies, then is "Hear Ye Hear Ye" by Red Mitchell Harold Land Quintet any "better known"?
@hotei
If the Peterson, Pederson, Pass trio counts, then what about "The Unforgettable NHOP Trio Live"? Ulf Wakenius plays brilliantly on this release but his name is nowhere as familiar as that of Joe Pass. Does this make it "little known"?
