string quartet playing in an underground pedestrian walkway

string quartet playing in an underground pedestrian walkway. The quartet consists of two violinists, a cellist, and another violinist slightly removed from the others. The violinist on the left is a man with short dark hair, wearing a black shirt and black pants. The violinist to his right is a woman with long blonde hair wearing a black dress and white sneakers. The cellist is a woman with long hair, wearing all black, seated in a folding chair. The other violinist is a bearded man in all black. Each musician is playing their respective instrument, and a speaker amplifies their sound. There is a black case open on the floor near the first violinist, presumably to collect money from passersby. In front of the last violinist, there's a container with a sign and QR code. The walkway is tiled with large gray and pink slabs. A poster is on the wall behind the first two violinists. A map is on the wall behind the cellist. There is a doorway at the far end of the hall, and a staircase on the right. There are a few people walking in the background. The ceiling has parallel, linear light fixtures.
