Old news to almost everyone here, but this SACD is superb. I listen to music almost exclusively using Carver's sonic holography (and time delay), and the drum solos on both of these albums appear close enough to touch right in front of my listening chair, and the instruments are panned wide to the right and left and discretely located in space. A wonderful experience, and another example of how recordings from the 50's and 60's are somehow more alive than many of the newer recordings.
