If the song you're making a video for ends with a dramatic fade of the instruments and you want a suitably dramatic ending then you could try the good old tactic of having you lead singer bow their head while the lights dim and the camera pulls back to reveal - ah ha! - that the band was On a Soundstage All Along. Thus you reveal the artificiality of the music video and undermine the video's story with an unsettling note of self-awareness. Or something. Anyway, it looks totally awesome. There seemed to be a glut of these around 2001-2005. Compare Proscenium Reveal.
