History of Rock in 100 Riffs

Games you can play while you watch this:

1. Name the era / realize when the era changes
2. Name that tuning (also: count the groping for the slide, shifting of feet for pedals)
3. How many of those songs did you you (or someone you know) spend hours learning on a fake, plastic guitar in Rock Band?
4: Count the amount of Jack White references.  Srsly.
