I'm a big Bessie fan, and have recently gone through the Frog label's eight volumes, which I really love. . . the sound is clearer than the Columbias, though the Columbia cds have those FANTASTIC notes from Chris Albertson with all those photos and record labels, etc. I confess, I have most of the Columbia sets, and all the Frog cds!
I love the sessions with Louis! And yes, that Joe Smith tone!
