The only superstar solo performer disco ever produced, Donna Summer projected a loud, sexy, and rebellious image that epitomized '70s disco. The double album "Bad Girls," her third two-record set in two years, was a sensation on both the radio and the dance floor. Disco-queen-turned-streetwalker, Summer had the persona that carried the album's two hit singles, "Bad Girls" and "Hot Stuff," to the top of the charts. The two #1 singles shot the album to #1, making Summer the sensation of 1979. One of Summer's greatest commercial successes, the album went platinum, selling over three million copies. Born in Boston, Donna Summer began her musical career in the German cast of "Hair" in 1968. First paired with Italian producer and arranger Giorgio Moroder in 1975 to record "Love To Love You Baby," Donna Summer added her gospel and Broadway experience to an electronic disco sound and created an entire disco genre of her own. Summer and Moroder collaborated on 11albums from 1975 through 1980, going their separate ways as disco fever faded.
