Here are the first four albums recorded by the Dukes of Dixieland on the Audio Fidelity label (earlier recordings were for Band Wagon in 1951, and Vik, an RCA subsidiary, in 1955). The first AF volume was "A Study in Hi-Fi Sound" and the second was "The Phenomenal D of D". Both were sub-titled "You Have to Hear it to Believe it", and those two comprise the first CD. The recording set-up succeeded in spotlighting each instrument in brilliant stereo, making the listener more conscious than otherwise of an over-enthusiastic drummer, and a rather weak clarinettist. A couple of the numbers run for over six minutes, and out of ideas.
Matters improve considerably with the second CD, thanks in no small measure to personnel changes, and a less harsh acoustic. It contains the third volume "Marching Along with the D of D", and the fourth "On Bourbon Street" (from which "Memphis Blues" has been omitted due to lack of playing time). The band is far more integrated, and the material receives sympathetic treatment. So despite my reservations about initial weaknesses, this generous compilation fully deserves top marks for value for money.
