Finneas revealed some of the hidden sounds in "Bury A Friend" and "Bad Guy"

If you need to be convinced further that Billie Eilish and Finneas operate on a completely different level than the average human, here goes. Along with vocals for days, the dynamic duo have taken the music industry by storm with a whole new genre of music that remains undefined and uncategorised. And, the reason for these blurred lines might just be the amount of audible layering that is used in their music.

Not solely relying on the old drums and guitar of yesteryear, the brother and sister seem to find music wherever they go. As Finneas explained to Jimmy Fallon, Billie actually recorded the sound of a drill during her dentist appointment and used it for her hit “Bury a Friend.” And, that “high-hat” in “Bad Guy,” is actually a traffic-light in Australia.

Honestly, how are these two geniuses walking among us?
