I read more into it and I guess someone was seriously injured at a show recently and the Slidebar doesn't have the insurance to pay for the injuries. I guess security told some people to stop moshing to prevent injury and the guys got hostile, so they had the cops arrest the people who were attacking the guards. It sucks the show was shut down. I guess the Deceased/Gravehill show is being moved to another venue so they won't have to worry about it being shut down.
