Inside a subway car, a young woman stands holding a microphone and singing, accompanied by a small, battery-powered speaker on the floor near her feet. She wears a white t-shirt, black jeans, and white sneakers, and carries a black backpack. Passengers surround her, some seated and some standing, several looking at their phones. The subway car is well-lit with overhead fluorescent lights, and features metal handrails for standing passengers. The general atmosphere is one of mild disinterest or tolerance from the other passengers.
