If the sound suddenly drops during the finale, do not blame the audio technicians. Most open-air arenas are bound by draconian municipal ordinances that dictate exact decibel limits at the property line.

It is a hilarious reality that massive, multimillion-dollar entertainment empires are entirely at the mercy of angry neighborhood associations with noise meters.
