Decadence
In the early 1970s, glam rock musicians such as David Bowie called themselves "decadent". David Bowie's 1973 album Diamond Dogs is about the theme of decadence.  Glam rock musicians and fans of glam rock music signaled that they were decadent by wearing platform shoes. The popular 1976 film Rocky Horror Picture Show was a humorous depiction of "decadence".
