Shellac Stack No. 90 is at least partly bound ’round with the Mason-Dixon Line. In addition to a few “Dixie” songs, we hear some ragtime quartets, some dance bands, piano solos, and even a slightly risqué “party record.” Featured artists include Willie Bryant, Eddie Duchin, Irving Aaronson, Joe Candullo, Alec Wilder, Al Jolson, and others.
