In 1999, the band began work on its final album, "Terror Twilight". Bob Nastanovich came up with the title, and has revealed the meaning of it in several interviews: "Twilight Terror is the short span between sunset and dusk; this is considered the most dangerous time in traffic, because half of the people switch on the headlights, and the other half doesn't. It's when most accidents happen." During an interview on the "Slow Century" documentary DVD, he said that the band was having trouble coming up with names for the record until he put forth "Terror Twilight". One of the final contenders was "Farewell Horizontal" (also the name of a 1989 science fiction novel by K. W. Jeter), and Nastanovich said, "There was no way I was going to be on the "Farewell Horizontal" tour for the next year."
