Live mic performance in a sparkly green dress, Pernik event

This is a vertical, full-shot video taken from a low angle indoors at what appears to be a party or event. A blonde woman in a sparkly green strapless dress is singing into a microphone. She is standing in the center of a dance floor, holding her left hand up in the air with her fingers splayed. To her left, a man in a white shirt and black pants is clapping his hands, illuminated by a blue light. To her right, another man in a white shirt and tan pants is also holding his hands up, facing her. In the background, other people are visible dancing and socializing. Some are on a mezzanine level above the dance floor, also appearing to be watching the performance. The environment is dimly lit, with stage lighting creating colorful effects.
