Disco Diva

"Disco diva" is a term about as dated as "disco" itself.

Whatever became of Studio 54? Grace Jones?

30 December 1977, New York Times, pg. C17:
At Studio 54 (489-7667), the $40 a person, by ticket-only admission will bring a champagne breakfast and a one-time performance by the disco-diva Grace Jones, which the fashionable discotheque promises will be filled with "the opulence of the Folies Bergere" and "a far cry from the traditional Guy Lombardo New Year's welcome."

18 July 1980, Washington Post, pg. C2:
Disco diva Donna Summer brought her life and her work one step closer together when she and song-writing collaborator Bruce Sudano married on Wednesday.
