The main act on a lineup who performs in the prime slot at peak time and whose name is used to promote the event.
The headliner is the main act on an event lineup, performing in the prime slot when the room is at its fullest and most energized. Their name is the primary draw used in event promotion.
Why it matters
Understanding where you sit on a lineup shapes how you build and end your set. A headliner inherits a warmed-up crowd from support acts and is expected to sustain peak energy, whereas a support DJ must build toward the headliner's entrance rather than exhausting the room.
