Disco music peaked in its popularity during the mid to late 70s. African American and Latin communities popularized the music genre at the time as a sort of rebellion towards the rock music that was dominating the charts. Disco music was heavily influenced by funk, Latin, and soul music and so was the dancing. When the movie “Saturday Night Fever” came out in 1977, disco dancing became the trend with moves like “the hustle”, “the electric slide” and “the bump”.
Steampunk is a type of science fiction that first became popular in the 1980s. Steampunk usually takes place in the 19th century, (usually Victorian era Britain) but instead of painting a realistic picture of the time, they paint it as more futuristic. In some stories people already have computers and television sets at the time and in others, completely fictional inventions exist instead.
