From PxTunes's 'GHOSTS vs. VAMPIRES' album! (https://pxtunes.bandcamp.com/album/ghosts-vs-vampires)

I had a ton(ne) of fun composing this two-phase boss-fight song!
Fun Facts: 'Full Moon Fight' and 'Organ of the Overlord' were also being considered as track names. The song was composed in 8/8 because I wanted to do a double time thing (intro and outro at 80bpm; rest at 160bpm) and my potato brain thought I had to double the beats per bar instead of half it... I was about five 8/8 bars too far to change it.
