The score is most unusual, not just for opera, but for music in general. The orchestra consists of the following:

* A 3-manual, 12-rank Barton Theater Organ
* A hybrid jazz traps and electronic drum kit
* An electric bass guitar
* Several synthesizer voices

Although the theater organ alone gives it a rich, eerie sound, when
combined with the other instruments, and talented singers on top of it
all, the electro swing sound achieved is really quite new!
