Mosaic can't just do what they did 30 years ago and expect the same results. When those BN sets (Blakey, Larry Young, McLean, etc.) were coming out, that was the only way to acquire that music on CD. Since then, just about all of the titles have been released on individual CD's. Same with things like the Columbia Woody Shaw (and the CBS box set greatly trumped the Mosaic in material with the extra disc, price, sound quality, and to me, presentation), the RCA Desmond, etc.
