Hellfire Follies is the 2nd soundtrack for Chapter 1 of Bendy and the Ink Machine. It was written by theMeatly.
The music is in vintage fashion while sounding similar to older, classical cartoons. The track consisted of instruments including a tuba, clarinet, and piano, with snare drums in the background.
The music can be heard when Henry approaches the projector from the filming areas of the workroom, suggesting that the music is coming out of the cartoon itself.
