"The Devil is a catchy lyric." This quote from the movie AMERICAN SATAN (Ash Avildsen, US 2017), when Mr. Capricorn (the devil) promises international success to a young heavy-metal band in Los Angeles and its singer, Johnny Faust.

In this article, two films from independent productions are analyzed to study how the devil reaches people through rock music and ultimately influences their actions. In addition, the temporal context and the events that affected the content of the screenplays are discussed.
