Curfew Penalties: Major arena and amphitheater venues (such as TD Garden or Fenway) enforce strict municipal noise curfews (typically 11:00 PM). Overrunning by even two minutes can trigger heavy union and municipal fines ranging from $1,000 to $10,000 per minute.

Pacing Curve: A typical 90-to-120 minute headline show opens with two or three high-tempo anthems (Act I), transitions to deeper catalog tracks, moves to a stripped-down B-stage acoustic break around minute 55, builds into an escalating crescendo, and reserves explosive hits for the encore.

Key Transitions: Watch out for adjacent keys that clash drastically unless separated by spoken crowd banter or an atmospheric playback interlude.
