For sound:
These recordings are designed for the era of shellac records of exceptional quality because they have already been recorded with the later LP similar technique, which was then used for radio broadcasts. There were they ever decades ago as a record and I am very glad that they are now available again.
For Booklet:
Well, the text could be a little more informative, but now there are Wikipedia ...
Overall, a highly recommended tasting a straighter border unjustly forgotten bandleader.
