Something awful is happening. The world might be ending. There's maiming and killing afoot. Screaming and cursing, cries for mercy, the sound of blood being spilled, gunfire, explosions. Faces twisted with fear, rage, and bloodlust. Bodies hitting the ground. It's a horrific situation.
But then, you see someone close or far away waving their arms around like they're signaling an orchestra. Often they are seen waving madly with a crooked smile or calm and serene as if they've found bliss. The violence and madness around is like music and the ones committing it are their instruments. In some cases, they are simply playing an instrument while others are fighting and killing to their whimsical tune. They are the ones conducting the carnage.
Likely to overlap with While Rome Burns or Dancing in the Ruins as the character in question indulges in their behavior in response to the chaos around them. Might overlap with the perpetrator being Wicked Cultured if there is classical music playing in the background/ brought up by the villain. If the world itself is crumbing, Watch the World Die can overlap, but the character is doing certainly more than just watching.
- In Hellsing, we have the Major. During the siege on London with the army of vampiric Nazi veteran soldiers against the forces of the Iscariot Organization, he proceeds to wave his arms in glee atop his zeppelin as the destruction of London and the slaughter of its citizens act as his music. The way he behaves during the act all but outright states he is experiencing pure ecstasy.

As the rest of his murderous gang goes on vengeful rampage outside, he mimics a conductor, describing the event as requiem to their late member, Uvogin, whom they didn't expect to perish at the hands of Kurapika. It helps that the background music playing as he conducts his requiem is Mozart's "Requiem" piece.

- In Fire Force, Inka Kasugatani comes into contact with the First Pillar and unlocks a new level of her Combat Clairvoyance that lets her predict explosions.

She even goes so far as to ask one of her henchman for stick to conduct the show.

He equates the screams of people suffering in the wake of his nightmare world to Rachmaninoff's number three in D minor, but "better".
- In Priest, the Big Bad Dhampyr Black Hat is 'conducting' the music playing on a gramaphone record while his vampire horde slaughter the entire population of the town of Jericho before battling and crucifying a few Priests.

- Doctor Who: Happens twice during the Tenth Doctor's run:
- In "Rise of the Cybermen", Mr. Crane has "The Lion Sleeps Tonight" played loudly throughout his facility as mind-controlled humans march helplessly into booths where they are gruesomely converted into Cybermen.

- In Supergirl (2015), Lex Luthor does this to the background tune of Mozart's Eine Kleine Nachtmusik, K. 525: I.
