Let’s Have Fun Before The World Ends: A Bummer City Newsletter I went to see a band called Turnstile in Chicago back in October. They played to 5,000 people. I saw them in October of last year, in a smaller venue that only held 1,200 people. Turnstile was formed in Baltimore in 2010. So that means it took them eleven years to get 1,200 people to see them play, and just one more year to 4x their crowd size into 5,000.
