Bad Girls  by Donna Summer

With her seventh album, Donna Summer departs from Casablanca Records in the best possible way. The Bad Girls of 1979 is a double (!) disco album that storms and dominates dance music lovers in the peak year of disco music. Songs like Hot Stuff and Bad Girls would be heard in clubs and parties for decades after their initial release. Bad Girls is obviously a disco album, but one can recognize that it established a subgenre of dance music, called Hi-NRG.

The album sold nearly 4,000,000 copies worldwide. Behind the massive success of Bad Girls lies one single person, Giorgio Moroder, who delivers his best in the production, elevating the sound and bringing incredible changes to electronic music. Of course, at his side is his close collaborator Peter John Bellotte. A few years later, New Order used part of the song Our Love for their own Blue Monday (!)

This double album reached No. 1 on the Billboard on June 16, 1979, where it stayed for a week and returned to No. 1 for five consecutive weeks from July 7 to August 11, 1979. It was obviously the “soundtrack” of that summer in the USA, and not only there.
