@adam_lazarus hello, i built this a couple weeks ago. i was just looking at the analytics and realized someone posted it here, sorry i didn't respond sooner. I live in new orleans and built it to help navigate the city during the weeks of jazz fest. @mrapierce is correct, the data comes from bandsintown.com but I'm not affiliated with bandsintown.com in any way, just using their data. I'm happy to answer any questions.
