Let's settle this once and for all.
"Djangology" by the Bluebird label has, to my knowledge, the best quality recordings of any Rome Session tunes. Better than the Intégrale by a long shot. Only 23 tunes on the CD, however.
The "Django in Rome" 4-CD box set remastered by Ted Kendall has noise removal, but they are very dark sounding.
The Intégrale series has less noise removal, but they're not as dark. More brightness in the sound.
"Djangology" by the Bluebird label has noise removal, but the tunes are still bright and fresh, unlike the Ted Kendall "Django in Rome" ones.
Some remastered tunes are borrowed from the "Intégrale CD:s" to "Django in Rome", while the "Djangology" remastering is all original. Basically, "Django in Rome" stole some tunes off the Intégrale set without remastering.
In conclusion: The Bluebird "Djangology" CD is by far the best in terms of quality, then the "Intégrale" series, and then the "Django in Rome" 4-CD set.
The reason for this is because when Ted Kendall remastered the tunes ( the ones which were not stolen from the "Intégrale" series), he removed a lot of the high-end by removing the noise which in turn made the recordings sound very dark and not very lively. The Bluebird "Djangology" CD removed the noise without getting rid of the high end.
The "Djangology" CD is a straight improvement over the Intégrale series while the "Django in Rome" set is a straight deterioration of the tunes compared to the other two candidates.
This is of course my own opinion.
If anyone has the name of any other CD with these recordings, please tell so I can make a comparison.
The "Django in Rome" recordings which were stolen from the Intégrale set are:
"To Each His Own"
"Oe Es-Tu Mon Amour"
"I Surrender Dear"
"After You've Gone"
"I got Rhythm"
"I Saw Stars"
"It's Only A Paper Moon"
"Time On My Hands"
"Darktown Strutters Ball"
"St. Louis Blues"
All the other recordings from the "Django in Rome" set are worse quality than the "Intégrale" set, (since this list was of recordings "stolen", so they are duplicates.) and of course the Bluebird "Djangology" CD.
Another thing to note is that the Bluebird "Djangology" CD has all the tunes re-tuned to concert pitch 440hz, unlike the "Intégrale" set, where all the tunes are slightly too high in pitch. So they're perfectly in tune. The reason for them being out of tune in the first place is because the recordings are old. The "Djangology" CD fixes this problem so you can play play along in tune on any instrument. Especially those that cannot be re-tuned.
