What followed a concert depends entirely on the specific event. Here are some possibilities:

• Encore: Often, the band or artist will return to the stage for one or more additional songs after the main set.
• Event Conclusion: The house lights come on, and attendees will leave the venue.
• After-party: Sometimes, especially for larger concerts or festivals, there's an after-party at a nearby venue.
• Meet and Greet: Some fans may have purchased tickets or won opportunities to meet the artists after the show.
