Fan was angry bc YG lost his voice (sore throat) at the very start of the concert and went backstage. Somebody threw ice cubes at him and he scanned the crowed and when he figured out who was it he jumped at him.
after that errbody started tossing bottles or whatever was in their hand(ice,bowls,cans,water etc.)
I didn't tape it all bc one of my friend fall victim to the flying bottle and blood was all over his face. We were dancing near to the stage and all the flying bottles were coming at us so we thought who cares for a damn video, protect your mf asses first lol.
