Two teams
Five Montreal artists in the red corner, five in the blue. Each team walks out behind its color.
Head to head
One artist from each corner per round. They perform back to back, same stage, same crowd.
The crowd scores it
Everyone in the room votes after every round. The scoreboard updates live on screen, then the next round starts.
Intermission
Halfway through, the ring belongs to boxers. Two professional matches, then the battle picks back up.
