large crowd of people attending what appears to be a concert in an indoor stadium or arena. The crowd is dense, and many individuals are holding up their phones, presumably to record the performance. Numerous lights, possibly from phones or the stage lighting, are visible throughout the stadium. Individuals appear to be singing along and enjoying the music. A metal barricade is visible near the camera, separating it from the crowd. Some people in the foreground are wearing black clothing, while others have a variety of outfits, including a light blue shirt and a zebra-striped top.
