A group of people dressed in traditional clothing perform on a stage during an outdoor nighttime event. They hold white cloths in their hands, moving them in unison to the rhythm of music. Behind them, a large screen displays a banner with text, indicating the event is a celebration of the 150th anniversary of the April Uprising in Panagyurishte. The stage is lit by colorful spotlights, and the environment is dark, with the audience visible only as silhouettes in the foreground.
