The sacrifice

At the climax of a German or Austrian death/black metal concert, this is the act in which the headlining band torches the entire front row of spectators with a flamethrower. These are the steps: 1.) Lead vocalist lets out a blood scream 'Sacrifice!' (The front row goes crazy, they are ready to meet Satan). 2.) He burns the front row alive with a flamethrower 3.) They continue the show
