Collectables CDs may have hurt the Mosaic sales. Collectable started selling these soon after the Mosaic set was available.
I have the LPs, but bought the Mosaic anyway. (I remember recommending these albums to Mosaic, so I had to buy it) Haven't check the total tracks time, but couldn't Mosaic have put all the music on 2 or 3 CDs instead of 4?
If the Collectables had been released first, I would have been satisfied with those discs. (even though they split the Paul Barbarin and George Lewis with other albums)
Don't the LPs usually sell for about $5? Doesn't seem like a rare or highly collectable set. (I do enjoy this style of music)
