Members of the original cast were not recorded until 1940, when Todd Duncan and Anne Brown recorded selections from the work. Two years later, when the first Broadway revival occurred, American Decca rushed other members of the cast into the recording studio to record other selections not recorded in 1940. These two albums were marketed as a two-volume 78 rpm set "Selections from George Gershwin's Folk Opera Porgy and Bess". After LPs began to be manufactured in 1948, the recording was transferred to LP, and subsequently, to CD.
