This is just a small portion of an elaborate, highly interactive infographic, designed by Brittany Klontz that details a history of rock by digging deeply into its most obscure sub-genres. As an added bonus, clicking on the name of a given genre provides you with a sample of the music, so if you’re looking for an example of German Electronic Metal or Crust Punk, the graphic can help you out.
