Live music performance in a Moscow metro underpass

Two individuals, a female and a male, are performing music in what appears to be a subway station or underpass. The female, standing on the left, is singing into a microphone positioned on a stand. She is wearing a dark brown long-sleeved top and light-colored pants. The male, on the right, is playing an acoustic guitar. He is wearing a dark green t-shirt and light gray sweatpants. A black amplifier and a guitar case are on the floor behind him. The floor is tiled with large grey tiles, and the walls are beige and tiled. A closed door with a red sign is visible in the background. Another person's back is visible in the foreground, observing the performance. The lighting appears to be artificial.
