Guitarist Lucas Brar took “The Imperial March” from Star Wars and rebuilt it from the ground up as a Johann Sebastian Bach-style fugue, and the reason it works so cleanly comes down to pure music theory: both share a 4/4 time signature, making the structural translation more natural than it might first appear. The result is unsettling in the best possible way, Darth Vader’s ominous theme rendered with the measured, interlocking complexity of baroque counterpoint, and the footage is exactly the kind of musical rabbit hole that justifies the internet’s existence.
