In an indoor, public space, a woman and a man are performing a musical piece

In an indoor, public space, a woman and a man are performing a musical piece. The woman, standing, plays the violin. She has long, dark, curly hair and wears a long black coat and dark pants. Her violin case is on the floor next to her. A small amplifier sits between her and the wall. The man, seated, plays a cello. He wears a black winter coat and a black knit cap. Behind him are a bag and a piece of wheeled luggage. They are performing in an alcove of a subway station. The walls are lined with rectangular white tiles, and overhead, a fluorescent light fixture casts a bright glow. A sign on the wall reads "#музыкавметро" ("Music in the Subway") in Russian.
