Who’s hanging out?

In a dimly lit room with red and blue lighting, a man in a dark shirt stands in the center, holding a long object that resembles a guitar, while another man in a light-colored shirt stands to his left. The man in the center repeatedly moves the object up and down in a rhythmic motion, as if playing a musical instrument, while the man to the left remains relatively still. A third man is visible in the foreground, partially obscured, looking towards the camera. The lighting shifts between red and blue hues throughout the loop.
