R&B crooner August Alsina was caught in the mix of a all-out brawl, at a concert that was supposed to promote nonviolence.

The singer was caught exchanging words with the shows promoter Cannon Slim, who was allegedly mad that Alsina was late to the “State of Emergency 2” concert.

Slim allegedly swung on the singer and a fight erupted. Alsina jumped into the fracas, but was swept away by his own security.

In the footage, Fabolous can be seen watching the drama from his dressing room.

Alsina eventually performed for the crowd.
