stage at an event, possibly a concert or festival, with a large LED screen displaying vertical white lines in the background. Above the screen, a Red Bull logo is visible. In the foreground, a dark platform or barrier with the word "METROPOLIS" in large, illuminated white letters is present. Several people are standing on the platform, some of whom are interacting with the audience or each other. One man on the left is raising his hand with his fingers spread in a gesture, while another man in the center is holding up a phone, possibly taking a picture or video. A woman on the right is also raising her hand with two fingers extended. The lighting is dramatic, with spotlights and stage effects creating a hazy atmosphere. The overall impression is of a lively event taking place in a large indoor venue. The location is identified as Sofia, Bulgaria, suggesting this is an event held in that city.
