Moore based fiery walls on the following quote from Edgar Allen Poe's The Pit and the Pendulum:
“I struggled no more, but the agony of my soul found vent in one loud, long, and final scream of despair. I felt that I tottered upon the brink—I averted my eyes—…There was a discordant hum of voices! There was a loud blast as of many trumpets! There was a harsh grating as of a thousand thunders!”
This work was the first piece I began working on in the process of recording the album, and how I determined the framework I would use for preparing these works. When I started, I tried to dive in and perform the piece with the electronics from the beginning wearing big headphones and loaning a great deal of my attention to a computer screen.
After self recording myself several times, I noticed I was losing dynamic contrast, intonation control, and general musical nuances. With this information, I decided the moving forward it would be best to learn the music separately from the electronics. With that in mind it became much easier to exaggerate the excellent musical elements of the piece, which helped activate some of the interactive electronics.
