Ted Kendall is not involved with this project, Andreas Meyer has done the transfers, the eq, and the mastering.
Here's what the Producer's Notes say about the source material (mainly metal parts, some 78s and tapes, etc.) I haven't listened to the samples, I'll wait for the set.
Producer’s Note: This set brings together all the Decca studio sessions by Louis Armstrong before joining RCA Victor in 1946. The disc sources for this package came from the original Decca metal parts. In some cases, either because the metal was damaged or because it was missing from the vault, a 78rpm pressing was used.
For sessions (QQ), (RR) and (SS) we were unable to obtain the original sources because of a devastating fire that claimed the life of metal parts, lacquer discs and various configurations of tapes. This is why we have had to utilize second generation LPs and CDRs as transfer sources for this set.
The source of this discography comes from the excellent publication All Of Me – The Complete Discography Of Louis Armstrong by Jos Willems (Scarecrow Press, 2006), and The Decca Labels by Michel Ruppli (Greenwood Press, 1996). Other entries in this discography came from research by Dan Morgenstern and the producer.
