What's the purpose of "torture dance" in Golden Wind? I've been following JoJo's Bizarre Adventure anime this season, it has 39 episodes total. It's currently on episode 11 (as of December 14, 2018).
I am confused with the dance that Narancia did with Fugo and Mista, while torturing Zucchero's head that got separated from his own body but was still alive, thanks to Bucciarati's Stand: Sticky Fingers.
What's the purpose of that dance and music towards Zucchero? When I listened to the music, it sounds like it's not a Japanese song, I didn't know what language they used. Does the dance have references from some sort of real life dance? Or is it just an original dance? Here is the scene when Zucchero gets tortured.
The purpose of the torture dance was a weird thing revolving around something special.

If you look at the art that comes in the dance, it indicates Narancia's, Mista's, and Fugo's stands tormenting Mario Zucchero.


Narancia Ghirga-Aerosmith
The art in the cut-scene indicates Aerosmith's bullets shooting towards him


Mista Guido-Sex Pistols
The art represents a cross-hair on the eye which indicates Mista's accuracy with his stand


Pannacotta  Fugo-Purple Haze
The art seems to indicate Purple Haze's burning poison ability as he is burning Mario Zucchero
