I know this has been done before, but with the state of the search function, it's very hard to find. I'm interested (as I'm sure others are) in getting recommendations for early jazz on Frog, Jazz Oracle, Hep, Timeless, and other labels that both present good but somewhat obscure music and do so in a proper fashion - excellent sound, historical background, etc.
I do have some favorites my own, but there are other folks here who are much more knowledgeable than I. Please post your recommended favorites from or comments about the above and similar labels. Many thanks.
