I was there. A few songs into ETID set a fight broke out between a couple guys. It spilled from the main room out onto the patio outside. I was standing sort of close to the door so I could see them at first. It lasted for like a minute then it seemed like it was done. But like 2 minutes later more people started rushing out onto the patio area (but I couldn't see the part of the patio where the "action" was). A few seconds later a kid ran inside tapped his friend next to me that they should get out of there (which in retrospect makes sense). Right after that the house lights came on the band said "Thank you. We're done." and walked off stage. A minute later the lead singer of ETID came back out and said they had to stop because somebody pulled a gun. I never heard any gunshots and nobody acted like shots had been fired (not saying shots weren't fired but it didn't seem like it).
