I downloaded the Flac version of the Pristine Audio 1944 Carnegie concert: I think it's excellent. I a/b'ed it with the Prestige cd: the Pristine Audio is brighter, with detail I hadn't heard before. The source material, like almost any live recording from the period, has inherent limitations; despite the famed Carnegie Hall acoustics, the recording was a bit muffled and thin. But the Pristine Audio version is a real step forward in hearing and appreciating a wonderful example of the Ellington band. Well worth the download.
