Darth Vader Theme {Alix1} I believe...
It is as fast as it needs to be, it is a good remix of the Imperial March, and goes well with the austere background of the Dark Lord. My only concern is that you remixed the Imperial March instead of coming up with something else for him entirely. However, if your intent was to remix the song, and the idea of it being Lord Vader's them came after, then that's understandable.
Overall, brilliant
