I agree with Mike's comments Al and would probably sell the grandmother before parting with this particular Mosaic. As well as the fantastic booklet with nice Francis Wolff session shots, I particularly like the track ordering of the Mosaic. For example, CD 1 starting off with 'Land of Nod' is an amazing 'declaration of intent' that sets the scene for the rest of the set.
I find the sound of the CDs OK too - don't have any of the RVGs/Conns to compare only vinyl for these sessions. If I want high-end sonics I dig out the LPs. For back-to-back non-stop Hill listening pleasure, the Mosaic's the one.
