It seems like summer music festivals get more and more popular every year. I guess this could be the subject of its own post, but let’s stick with my personal anecdotal evidence for the time being. I remember only a handful of music festivals in the U.S. when I was in high school - Bonnaroo, All Good, 10,000 Lakes, and Coachella. I am sure that there were others, but it was nowhere near as ubiquitous as present day.
