Darth Vader’s “Imperial March” Played as a Bach Fugue

Postscript: 

And now for some music written by and played by real people…

This is great. This guitarist (who I’ve seen before somewhere) upgrades Darth Vader’s theme from Star Wars into a Bach fugue. It’s technically impressive. And it’s edifying. I’ve heard “Bach fugue” defined before, but it wasn’t until I listened to this short piece of music that I understood how it works.
