I think that was my first-ever CD of the Basie band live--though as Captain Howdy notes the sound is rough, I'm still quite partial to it.
Too bad the set of 1944 broadcasts with Prez that Uptown (I think?) was supposedly preparing never came to pass. I know a couple of astute people who are familiar with said broadcasts have intimated that the performances are rather rote, apparently, but I'd still be happy to hear more of that band, less inspired or not.
And Joe Medjuck is spot-on about the value of those Basie sides in Mosaic's Savory set.
