Act as a dystopian visual artist with expertise in atmospheric storytelling. Create a hyper-detailed image of a lone musician playing a battered acoustic guitar in the ruins of an old theater. The scene should evoke a sense of melancholy and resilience, with [CRACKED MARBLE COLUMNS] framing the stage, [DUST-LADEN SUNLIGHT] streaming through a collapsed ceiling, and [TATTERED RED CURTAINS] fluttering in the wind. The musician wears a makeshift outfit of scavenged clothing, their face partially obscured by a [GAS MASK WITH A BROKEN LENS]. Include subtle details like fallen playbills, overgrown vines reclaiming the seats, and a flickering oil lamp providing the only other light. Render in a cinematic style with muted earth tones contrasted by the warm glow of the lamp.
