This is not really a "music" album, but it's an invaluable document. From 1956:
It very much has a natural, almost eavesdropping feel to it, right down to including an Amateur Night segment that is indeed that.
That would be my personal assessment, yes. I think Byas was tremendously important and consistently enjoyable. And by definition, more "modern" than the Chu.
Having said that those Vanguard records are certainly enjoyable or better. And there will, again by definition, have a variety of solo voices.
