There was no decision-making process. The singer of my sludge metal band said some shit about my mom on the mic. With her in the audience.Next thing I knew, I was off my drum stool and punching him in the face.Then the guitarist and I almost got in a fight onstage. I got my drums packed into my truck and peeled off just as two police cruisers pulled into the parking lot. Of course, the police put out a warrant for my arrest.
