Why just why

A man in a red beanie stands on a dimly lit stage with a ladder to his left and a drum set to his right, raising his right hand in a gesture. The scene cuts to a man in a black beanie singing into a microphone, then to a man in a white cap and black gloves adjusting his gloves while looking at the camera. Next, a man in a red cap and sleeveless shirt plays a drum set on a dark stage. The scene shifts to a man on a brightly lit outdoor stage at dusk, playing a guitar in front of a large crowd with city buildings in the background. Finally, a man in a black hoodie walks down a plain hallway.
