I think that is absolutely it. There are so many RVG titles now that only Mosaic could do a 60s BN box justice. Name an artist that you cannot find anything on CD by. By my count, The Three Sounds are the only seriously underrepresented Blue Note artist on CD. Individual titles or minor BN artists are ending up on third party reissue labels, so slowly but surely, everything is coming out.
I would like Blue Note to revisit some of the funky 70s stuff.
