In the 1970s, before the age of music television, labels distributed "promo clips" to promote their artists' latest singles. Since there was not yet a market for "story" videos, these clips most often consisted of live perfomances spliced with other footage.
Despite the creative limitations, some truly great videos did come out of the decade. Blondie's "Heart of Glass", for example, brilliantly captures not only Debbie Harry's star wattage but also New York City nightlife at the height of disco's popularity.
Rasputin
Boney M.'s "Rasputin" is memorable not only for it's exotic locale but also because of it's quick cut editing. It is, in fact, one of the earliest examples of this style of editing that would become so prevalent years later on Music Television (MTV).
Ironically, it was pre-MTV era televsion that provided us with some of the best 70s videos. Amii Stewart's performance of "Knock on Wood" on "Midnight Special" was a choreographed spectacle that was decades ahead of it's time. Similarly, shows like "Solid Gold", "Top of the Pops", and "Wetten Dass" captured some of the greatest disco divas at the peak of their stardom.
