Pacer

"Pacer" is the fourth song from Act III of the The Smashing Pumpkins' 2023 rock opera, ATUM.

As with several other songs on ATUM Billy Corgan has said "Pacer" likely wouldn't have been written had it not been for a rock opera project, as it deviates so much from typical Smashing Pumpkins material. As for the title "Pacer", Corgan initially thought it would be just a working title, but later decided to keep it given the "pace" of the song.

Synopsis
June, for the first time, is forced to come to terms with her own death. She wonders if following after Shiny was worth it in the end. As her and her ship begin to burn up by the heat of the sun. Although, it is implied that June does not actually "die". It is a different type of "transformational event" that is separate from the traditional death we've come to expect.
