Live indoor concert with Bulgarian flag backdrop in Tsarevo

The video shows a concert or performance taking place in a dark, indoor venue. A large screen behind the stage displays the Bulgarian flag waving. A solo female performer, dressed in a sparkly outfit, stands on stage, facing the audience and holding a microphone. Green lights are projected onto the stage and the audience, creating beams of light. A crowd of people are visible in the foreground, silhouetted against the stage lights, with many holding up their phones. Some members of the audience appear to be dancing or raising their hands. The overall atmosphere appears to be energetic and celebratory.
