Saturday Night Fever: The Autumn of the Disco Era

Saturday Night Fever was not only a watershed moment for the development of disco, but it also proved that soundtracks could be commercially successful on their own. This was a revelation for the music industry, offering an extra revenue source and a separate marketing channel. It helped to kickstart or revive flagging careers by including the right song on a hit soundtrack.

For film companies, a hit movie soundtrack could be a powerful marketing tool. Although it could not save a film, as seen in episode 113 about Dan Hartman and Streets of Fire. When it worked well, magic happened. At the start of the eighties, one man was responsible for a few sublime examples of that magic: Giorgio Moroder.
