from my own experience the LPs, as Chris is implying, are hit or miss - however, there are some great transfers on them as well as some lesser sources - I think Doug Pomeroy told me that Columbia had destroyed a lot of the Bessie masters. I also have a Japanese boxed set of the Bessie sides that I have not listened to in some time, so I can report back. The CDs, as Chris indicates also, are a mixed thing - some good, some bad. The JSP Davises is excellent - John R.T. was a great transfer engineer and, most importantly, he had 78s that were in mint shape - also, there is/was a European guy (who I've lost touch with) who had these strange old vinyl 78s that they produced in small numbers back then. There is a whole CD of Bessie material taken from these, and the sound is spectacular on them, best of all sources -
