Summer's Gun is a track based off of the book Billy Summers by Stephen king. The tale of the song follows what would be considered the four "parts" of the book, each part with a different tone- Hip hop for the first and second (accepting the job and uncovering Majarian's treachery respectively), which blends into dubstep for the third (marked by the scream of what could be assumed to be Alice), and finishing off with a few bars of trap that leave the question of what is next for Alice.
