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.
