A live music performance unfolds on a stage bathed in red light. A singer, center stage, dressed in dark clothing, belts out a song. Behind her, a large screen displays images of what appears to be a European-style mansion. To the singer’s left, a man holds up the Bulgarian flag. The stage is flanked by lighting rigs and audio equipment. A small crowd gathers in front of the stage, some recording with their phones. Logos of sponsors are displayed at the top of the screen. A disco ball is suspended from the ceiling.
