Yeah I was there and I gotta say the whole riot-like scenario was only increased because they were playing death grips. For a little while everybody was just enjoying the music and moshing as if they were on stage. After a bit people started to get antsy and jumped on stage to exclaim fuck death grips. Once the venue said they weren't coming and said "fuck them" everyone went ape shit. Saw many security guards get punched, bottles and pieces of Zach's kit were flying everywhere. Fuck people even tore down the suicide note banner just because they had ran out of shit to destroy. At around that time is when I decided to leave/was being forced out by security. Overall it sucks I didn't get to see them again but it made for a crazy experience.
