street scene in what appears to be a European city

street scene in what appears to be a European city. Two men are playing guitars and singing on a sidewalk next to a building with arched windows and awnings. A microphone and speaker are set up in front of them. Across the street, outdoor seating for a cafe is visible, with patrons seated at tables. Several people are walking down the cobblestone street in both directions. In the background, an ornate building with classical architecture, possibly an opera house, is prominent, with a banner that reads "opéra de lille" hanging from it. The sky is clear and blue. The lighting suggests it is daytime, likely afternoon, with sunlight casting shadows. The atmosphere appears lively and public.
