I ordered this set for two reasons.
a) I have money in the bank, still. Seems miraculous. Something to celebrate with a nice jazz treasure.
b) I have the Glenn Gould Columbia "Original Jacket" box set, and LOVE it. This seems just like it, and will probably sit right on the shelf next to it, and will be very convenient for listening to Miles Columbia discs.
Additioinally, I'll have fun and practice my concentration by comparing cd issues on Columbia and Sony of these titles. I know that there are at least a half a dozen to a dozen that I can sell or give away and keep the box set versions. Maybe more, I have lots of Sony Miles cds, many of the US, and all the boxsets.
